If I am the least bit representative of the typical newcomer to DCC, who doesn't necessarily take the time to figure out ahead of time which system would be a good/better fit, the majority of us go to a retailer and explain what we want, and the retailer says, "Why, I just happen to have received Brand SpiffiDCC yesterday....no, today...yesterday...yeah, yesterday. They are supposed to be really good. I can give you a sweet deal. They list for $999.99, but I can give you one of these babies for just $180. Whaddayasay?"
An hour later, excitedly holding the manual upside down and being oblivious to it, our intrepid modeller is hell-bent on running his DCC locomotive by supper time. And you know what....run it does...just as the manual says it should. From that point on, not a single one of us looks back, unless he comes to a realization that he needed the 5 amp model, and not the 1 amp model. Anyone care to guess which ones I am talking about? From personal experience?
