I use NCE DCC 10 amp system and it has worked reliably for 17 years on a 24'x26' layout. Most 0 scalers I know use NCE DCC.
If you want to run DCS on 2 rail, there have been a few threads about that lately on this forum.
I also use the NCE 10 Amp system and I like it a lot but what Tom Dempsey said is true. If you can get a 5 amp or more power supply for your Digitrax system it should work fine. That is the beauty of NMRA standard protocol.
