I'm in the market for a quality product and I was wondering what people thought about the Proto 2000 and Athearns premium locomotives. They both seem do have the same qualities but Walthers of course touts theirs as revolutionary. I noticed that Walthers seems to be out of what I want but my hobby shop may be able to get one. Athearn seems to have theirs in stock and my hobby shop is pushing it; even going so far as to give me the stores catalog to take home. I'm sure both are very fine products but maybe there is a reason Walthers is out of stock; beyond being $15.00 cheaper that is.
