Guys I need some help. I want to purchase an F7 A/B unit/set , or similar, and have no clue which is good, or which is crap. I am looking at the Micro-Trains EMD FT as that is close to the style and color scheme I want. What are your views of this outfit? There was another company I was looking at, but I can't find it right now. It may have been from Intermountain. Any help on this would be appreciated. I know so little about all this yet. I am learning, but there is also a train show in Allentown, PA this weekend and just in case, I want to be prepared. Thank you for your help and input, MrBones "SouthForkRR"
