Okay guys, I'm seriously thinking about making the DCC plunge now, while my motive power fleet is still relatively small. Got a couple questions for y'all before I do, however. Right now I see three entry-level DCC systems, from MRC, Digitrax, and Atlas. How do they all compare? I guess my biggest concern now is expandability over anything else. Right now I have no DCC-equipped locomotives, but in short order I will most likely have an Atlas SD35 equipped (with a replacment circuit-board decoder) and two or three Atlas GP38's (factory-equipped with decoders). I also have an Atlas/Kato RS-3 & GP30, a Life-Like SW1200, and a Atlas GP9 that I'm scratching my head, figguring out how to equip. Any suggestions? Any pointers and tips you could offer would be much appreciated!
