Since many on here are promoters of Sunset /GGD, Atlas, and Weaver engines with TMCC, not sure how big of a draw Legacy is to folks other than the Lionel fanatics. With many here claiming the day of the hand held is over and WiFi the future, is the Williams no hassle WiFi remote control really the coming thing? You are not locked in by a manufacturer then correct? If TMCC had been produced with 100 speed steps, would anyone even care about Legacy having more? Many of our DCC friends want guests to drool over their 1 mph creeping big boys and challengers. (If the UP ran those engines at 1 mph so much the Rock Island would have taken them over)
Quickly the guests say "nice, is it broken?" when looking
If you have a layout for friends to run on too, you will have to have all these systems.
