Everyone debates the issue of DCC and DC. Does anyone have an opinion on this new system from Crest? I guess it's the same thing as DCC except the inofrmation to the engine is radio contrlled instead of through the rails. Is this easier to learn and do than DCC? I do know you need a DCC ready engine to switch the chip out so it will work. It just seems a little less expensive. I could be wrong though.
