May I suggest the Sony 610 remote. It doesn't know Bryston out of the box but it can learn from your existing remote(s). The build quality and aesthetics are far better than Logitech. It's also half the price of the cheapest Logitech.

That is of course if you have a remote (from the original device or if the universal remote can do codes). It depends on which Harmony you are talking about. I easily prefer the Harmony One vs. the Sony. The Harmony 890 I have which I keep in the bedroom and use for the bedroom and basement systems is not quite as good as it is not touch screen and the layout is not quite the same. Of course the Harmony remotes are more money and don't make sense if you don't have enough devices to make it worth while. I've seen refurbished ones at Tiger Direct. I bought my BDA-1 lightly used without a remote for that reason. I sold my BCD-1 and did not need to worry about spending an additional dollars for a unit with the Bryston remote, order the Bryston remote and then need to get a universal one too. I had Pronto remotes for quite a while. I like certain things about their flexibility vs. Harmony, but they take much longer to set-up to use in a manner for a device. Once you decide on the Harmony, you pretty much know you don't have to spend much time setting anything up to getting something else to control what you need.
