The B&W DM601s3 is surprisingly not bad. I had the 602s2 and was never satisfied with it, but the 601 Series 3 is a much better monitor, in my opinion of course. You could probably find a pair used within your budget. The good thing about B&W is that you can sell them easily should you decide to upgrade (personal experience).
Usher S520 gets recommended on this forum a lot but I've never heard it. And then there's the Onix/AV123 stuff like the Reference 1 or X-LS which have gotten good reviews for budget gear. Lots of options.
Good luck.
