Like I said, the past two decades have brought more new products and technology than ever before. So, we've gotten spoiled. Now there's an expectation (and subtly, a demand, for this continue). Look at the culture we live in: drive through everything, fast food, fast communication... have it YOUR way.
Brian,
We are not sheep, we are the ones paying our hard earned money, so I think if a company wants our business then we deserve it our way. If not, we take our money elsewhere.
MTH's and Lionel's lack of attention to detail in their higher priced offerings, especially on their locomotives, is why there are almost none on my layout. Instead, I have very happily, purchased items from 3rd Rail, Atlas, and Weaver, and even K-Line. (I will add, however, that I do have my eye on the new NS ES44AC in the 2015 Lionel catalog. ) When we talk about locomotives, a lot of times, fidelity can be achieved by add-ons to the basic shell, so its not always a matter of creating entire new tooling for an engine. Many of the other, smaller, manufacturers understand this. Lionel, too, seems to be coming around, as demonstrated in their plans for the SD40 in the 2015 Signature catalog show.
I have scale models of trains that I never dreamed would be manufactured, like the 3rd Rail Columbian set and the 3rd Rail Train of Tomorrow. So, heck yea, I'm happy with the hobby.
Jim
