So kinda out a luck huh? I'd b better off buying one sound ready? Then there's the Q of can I get one that runs analog, or should I just upgrade that now too and use DCC? I have ran N scale off and on in mid 90's but the cool digital stuff for this has been perty tough to get caught up on. I feel like my dad when he finally went to dvd, lol. Anyway recommendations for a decent priced stater DCC/transformer would be appreciated. thanks again 

Hello, I'm new to railing. I have a Bachmann GE B23/B30-7 Diesel loco (N scale).
I want to add sound but am having trouble locating a decoder that will work for sure. I am currently running analog layout and if I could get sound for that, would be great. If I need to upgrade to Digital command could you also recommend one that is more affordable and also work well with sound decoder. Digitrax SDN144PS - sound and motor with the plug cutoff and hardwired was recommended or replace the factory board with a drop-in board like the SDN144K0A. If I have to do any soldering I would like to see installation process or be sure before I buy that I could do this. If available, a plug and play would be great. Any help would be great. thanks for your time.
