What method(s) have you found work best at tracking down those rare, hard to find NIB or used 3-rail items on your must have list? Besides the obvious word-of-mouth networking with fellow club members and visiting the LHS, train shows, auctions and swap meets - what else has worked for you?
Not asking you to divulge any "coveted" secret sources, but in addition to OGR (and excluding the bay) - are there any internet sites worthwhile checking for used 3 rail items (locos, cars, sets, accessories)?
Any particular train or railroad "FOR SALE/WANT TO BUY" forum sites besides those here at OGR that you'd recommend?
