I've got nothing but good to say about my pronto remotes. I started with a TSU-1000 many years back for my living room theater, and am now using a TSU-7000 for my new home theater. The 1000 is still upstairs, but the only complaint I have with the old model is the brightness is not where it should. Of course that's been long since resolved in newer models.
The only reason I can think of that it would receive negative comments, is that it's a bit of a pain to program and customize if you want to get fancy. I'm of course biased, so you should check out
Remotecentral for reviews on the various remotes out there. Remotecentral also has templates for the pronto remotes so you can download and tweak it for your setup instead of starting from scratch.
