I haven't had the "best" experience with the Bachmann Spectrum 2-8-0.  I purchased my NYC 2-8-0 DCC ready, and used so it was already broken into. About 2 months later I put a DH123 decoder into it. after a month or so the engine shorted out!?? So I mailed it in for repairs in February and still haven't got in it back yet. So, I can't really say there the best. 



P.S.
( Does anyone know how long it take to get back an engine from Bachmann when you send it in for repairs?)
