I think you've got some fine choices listed already.

I think I'd be inclined to go with some of the more inexpensive amps in that section -- my opinion is that, with exceptions, there isn't that much difference among the various amps ability to reproduce sound. At least among your typical home audio amps from reputable brands. Will the Bryston sound better than the Rotel? Probably.. a little. But probably not enough to justify the extra cost. But then I'm professionally cheap (I'm a CPA after all).

All of the brands listed also have a good reputation (from what I know) for being built well, so you should be ok with any of those brands buying used.
