I am thinking about getting into model trains..HO scale. I am looking for material suitable for a beginner on DCC. I have the 3 disc series, "Building a Model Train" by Green Frog. It is pretty good, but only a small section on DCC and not well put together. I obtained the booklet, "DCC Made Easy" by Lionel Strang...which is pretty good. I really would like to get a very good book or, better, a DVD for beginners on the basics of DCC. Any suggestions?
