Thanks guys....this is fun learning and reading about all the DCC systems.
I have no doubt DCS is a great system for 2 rail and 3 rail, but I really only want one system controlling my trains...so if I went to DCS, I would be limited to MTH engines only. If I go anyones DCC I can run any 2 rail engine with DCC even -2 MTH engines especially with P3 and scale wheels.
I can't decide which system to get, but I am going to have fun figuring it out. I do know I want wireless. Even though NCE and DigiTrax can have multiple connections across the layout, wireless is nice...and to me worth the extra expense.
If ESU is 7 AMPS and come wireless at ~$389 vs NCE 5 AMP system wireless at $550...the NCE would have to be head and shoulder better to justify the $200 difference...
For those that have ESU, is it easy to add another 7 AMPs of power for future upgrade? I saw a video of the NCE and it is plug and play (I think).
