decoder help...

i’m going to be buying the Bachmann E-Z Command Digital Command system mainly because of price.

I have a Bachmann 2-8-0 Consolidation spectrum N scale
and an Atlas N 2-6-0 mogul steam loco

witch decodes will fit into these engines?
Is there a sound decoder that will work with either of these (sound and moter control)?
Thanks

check out http://www.tonystrains.com/ for help, he can tell you exactly

Any speaker small enough to fit into an N-scale locomotive or tender is going to be too small to have good sound characteristics. As a general rule, sound decoders are for HO scale or larger.
