Back in 1982 I bought a F3 or 7 freight set for my tiny Christmas tree. I dabbled a little through the years with my kids, but being the Military I was often deployed. I'm now retired and wanting to get back into the hobby with my grandchildren. I know that my set won't run worth a hoot, so my question is: Do I stick with DC or spend the money piecemealing a DCC set together?
