Here's my 2 cents on a couple issues in this thread.
First of all, since when are winning bidders vultures? Just like on any auction site, live or online, item goes to the highest bidder. The highest bidder does not do anything wrong, they simply bid what they think the item is worth. I can speak from personal experience, sometimes they win, sometimes they lose.
I'll give a couple examples from a Stout auction several months ago at which I won a number of items. As I mentioned in another thread, I bid on many items, because that auction (I think in November) had a wealth of Santa Fe items. So for example I bid $700 on a PAIR of Sunset E8s. I'm much more of an F unit fan, but for Sunset and Santa Fe at 1/2 price, I thought I'd give it a try. I ended up wining for $675. After commission and tax, I paid $832 out the door. Sold the pair on eBay recently for $1250 ($690 for the A and $560 for the B), and after eBay fees cleared $1093, for a "profit" of $261. Had the exact same transaction numbers (except the $1250 was $700 + $550) on a pair of F7s. So that's $522 profit on 2 auction lots. All together, of the items I flipped, I made a total profit of about $1700. However, what I spent minus what I got from eBay is about $3370, meaning that is the cost of the items I kept.
So what did I keep? A pair of Atlas F3s in Santa Fe (which I figure are worth about $300 and $150 at going prices), a Sunset Santa Fe 4-8-4 (which I think is worth about $700), a Weaver Santa Fe 4-6-2 (which might be worth about $300), an unpowered Atlas F7 (worth about $150), a 4 car set of Super Chief cars (plastic, worth about $400), and a 10 car set of Super Chief cars (aluminum, worth about $3000). So because of being able to flip, I feel like I got about $5000 worth of stuff I wanted for about $3300.
Now, on the most recent auction, the topic of this thread, I only won one lot, a set of Atlas WP F3s and 11 zephyr cars. If the zephyr cars only go for $130 and the engines only go for $300, I'll only make about $200 on this flip (which might barely cover shipping). If the zephyr cars go for more like $150 (at least one will go for $300) and the engines go for $400, I'll make more like $600. Ironically, the lots that I wanted to keep a couple items from I ended up not having the winning bid on. In particular, I was eyeing some of the older Atlas F3s in CB&Q, but didn't bid high enough, and one lot contained a zephyr car that I wanted, but that lot went for more than I thought I could make money on.
But even though some items went for more than I thought I could make money on, I think they were still a bargain for someone who was buying to run (at least for the lots for which I had an interest). These F3s I picked up, all powered, cost me less than $300 out the door, and the zephyr cars were a little under $100 each out the door. The main type of items that I thought were overpriced (but maybe that is due to my ignorance on this very niche market) was the brass traction items from The Car Works, many of which went for over $1000.
And I think that Greg made a great decision promoting the auction here. Sure the extra interest may have cost me a chance to make a few bucks flipping items like on the November auction, but he did the right thing for him and his auction house, and you can't fault him for that. I have to admit, when I saw his post here on OGR I cringed (because I was afraid the prices would be higher than in November). And by the way, the 19% buyers fee is only that high if you decide to pay online. If you spend a dollar at the bank and buy a money order (free at some banks) and spend less than a dollar on postage, he only charges 16%. That 3% difference can be a big deal on a large purchase.
If you ask me, the real vultures are the train show sellers and some brick and mortar retailers who insist on trying to get full retail for items that are readily available all over the internet for much cheaper. A very well known store here in So Cal has a plethora of brass items from a variety of importers. One that caught my eye was a Sunset Models Southern Pacific Atlantic steam engine. I own two of these little beauties, and neither of them cost me over $400. I asked the store owner the price, and he said (with a straight face) $750. When I gasped at the price, he assured me it was a really good price; I'm never going back. Had a similar experience at one of the large train shows at the fairgrounds. Gentleman claimed to know both Mort Mann and Scott Mann as he went on to explain why this Sunset Models consolidation was worth $800, even though I never see them go for more than $500 on eBay.
The other set of vultures are those will shills bidding on their items on eBay. But that is another story for another day.
The last thing I wanted to mention about fair priced versus overpriced, is that it depends a lot on the population of bidders interested in a certain item. I mean I know that kind of goes without saying, but here is an example. I watch several categories of items on eBay on a daily basis. One area of interest for me is the older Atlas reefers. Usually I pay no attention unless I can get the item to my door for under $50 (maybe $60 if it is very desirable). But if a certain road name came in 4 road numbers, and I have 3 of the 4 road numbers, and that one road number I'm missing comes up, then I'm usually willing to go full retail if needed on that item to complete that set. Someone looking at that from the outside might wonder why I paid $70 for a car that goes on eBay all the time for more like $40.
That's been my experience. Sorry that it was so sour for so many on this forum.
