Discussions are one of the fun features of model railroading lol. I miss the Friday night arguments (discussions ) at a defunct local train store years ago. But seriously I think morst railroaders want the digital sounds and controls. I have both and Have found some great bargains on the big scale size conventional locomotives. The GP30 is in demand now but later it might drop a little but considering when other companies are charging $200 is a pretty good deal for a sound equiped scale size locomotive and when you compare the Williams By Bachmann trains made today compared to early Williams they really came a long way.
