It's surprising that no one has mentioned the Evolution Acoustics MMMicros One's (also referred to as "Micro One"). If you look through the threads, you'll see that the issue is not whether they sound great - pretty much everyone who has heard them thinks they do - but whether they sound better than much more expensive monitors (many believe that they do). I've heard one system with them and think they're incredible for the money. Disclaimer: I own the big Evolution Acoustics MM2, so I obviously like the house sound.
As for other monitors in that price range, I also like the Dynaudio Confidence 1, but they need a lot of power to come alive, which is problematic because most high-powered amps use a lot of negative feedback, which I am very sensitive to and can't tolerate.
Both of these speakers use very simple crossovers that cause little phase shift - if used with the right electronics, they deliver truly high performance.
