Legacy is great--no argument there. But it ain't cheap. Legacy locos command premium bucks versus DCS PS-3 locos. Spending on Legacy locos and then running a CW-80 transformer is a confusing mix--rich at the running end and poor at the control end.

PS3 locos may not be as much as Legacy locos but they sure aren't free. In fact, they've gone up in value MTH's future in limbo.
It makes even less sense to buy DCS system to run Legacy locos when you still need Legacy base to do so.
With all due respect to Mike Wolf, his products are great, but this has to be one of the best instances of false marketing in history.
The DCS merely mimics the commands of the Legacy handheld sending commands through the Legacy base and requires more keystrokes and eyes to do so.
By clever design of the tactile feel of the controls. Once the locomotive information is loaded into the Legacy system. All of the "meat and potatoes" train functions can be accessed by feel as you watch your trains react.
There is no other command system in any scale that has that capability. For all the excitement over bluetooth and 'devices". This requires even more time looking at a screen than your trains.
Lastly, the OP wants to start out using the CW he has, certainly he can upgrade his transformer in the future like many of us probably have. Theres been no mention of layout size.
