Thanks for the replies Dave and Lee.
In my case, DCC isn't an issue since I'm solidly stuck in the stone age with DC. Oddly enough I find wiring layouts for DC fascinating, so that won't be changing soon
I do know that I would end up detailing it to match the prototype, so Bachmann wins in that department. Then again, the roadnames are limited (no Rock Island or Milwaukee) and doing a full custom paint/decal job is beyond my capabilities at the moment.
I'll try to compare the two at my LHS, especially with what Al and others have stated about the cab windows and body, perhaps seeing the two in person will give me a definitive answer.
Anyway, I'll mull over this while doing some patented armchair modeling, or just do the easy thing and buy a locomotive that only one company offers
thanks again,
Lucas
