Walter:
I agree with Tim. I was a complete beginner in this hobby a few years ago. I looked at what aristocraft said the 75 mhz system would do, and I invested in a bunch of the 75 mhz decoders. Turns out it never did exactly what was claimed, and shortly after I invested in it, Aristo discontinued it. I have a bunch of RX’s and two Tx’s which will eventually wear out. The 75 mhz system does work reliably, in a basic way. It just does not do what they claimed, and now it’s dead.
Now this kind of thing happens all the time–technology improves. I’ve got a lot of old VHS tapes and a player, gathering dust. But it made me a little suspicious–even though I have a lot of aristo stuff–3 locos and a number of freight cars, a lot of track. I think I can confidently say that the gap between hype and reality is a little wider with Aristo than it is with other manufacturers. One of the reasons I got interested in DCC was that it was a non-proprietary system. I could get decoders from various makers that would all run on my track, without having to get new transmitters. It manufacturer A went belly up, There were thre eor four othe rplayers in the game whose equipment would work.
That being said, the Revolution seems to be getting generally good reviews, and I would say that if you want to run on battery, and are not very interested in sound, it’s a good choice. If I ran on batteries, I would look at Tony Walsham’s systems, or I would look at the Airwire system, which allows you to run DCC. QSI’s decoders can be run on track and battery and include excellent sound for less than the cost of other solutions. Tony Walsham’s new Beltrol system can trigger the QSI sounds.
If you want to run on track power, it seems to me the Revolution is cludgy. If you want to add sound, it seems to me it’s behind the curve in terms of how it works. But I’m a track power/DCC guy, and I’m completely delighted with the way QSI/DCC works. QSI has posted a comparison on their website.

People run their trains really differently, and need different things. Battery never made sense for me; for others it’s the perfect solution.
