The two common complaints about the AR1 are that since they use a relay, they are slow and noisy.
However, I use two AR1's on my layout, and they work just fine - no hesitation or sound dropouts whatsoever, and you really have to listen to hear the "tick".
There was a recent thread on the AR1, where several other users also reported good results with them:

My suggestion would be to go for it.
I want to put a Balloon track in my yard in to turn my Loco's. Is the Digitrax AR-1 a good choice for this application? It is on the clearance table for $25.00 Would something else be a better choice? I have a NCE system. Thanks for your help.
