I think Rotel is a great band for the buck company but people say they can be pretty bright with the wrong speakers. I never thought so.
I the used market I can vouch for Primare, Creek (especially the CLASSIC 5350SE),and Belles Aria. I also loved a Prima Luna tube integated I heard in a showroom; but I didn't investigate the speakers it was driving as I was not there to shop that day.
I chose a used Primare I32 class D integrated myself. Very neutral, but frisky. There's one on ebay a bit over your budget, though. You could always make an offer.
