You can alsways go my route. I run a low budget backwoods RR. I use Bachmann Couplers and Bachmann wheels. The couplers might be too big to scale but to me it still looks good and to most people looking at your layout they dont know the difference. I have not had any problems. Kadee might look great and easy to work with but for the price of them vs. Bachmann you cant go wrong with the Bach. I forget the difference but it is a big difference in price plus you get more with Bachmann. You got great advise and it all depends on what kind of money you want to spend.
