You will get a lot of bang for the buck if you are willing to buy used speakers. I recently saw 2 pairs of ADS 710s here for less than $300. It would be very difficult to find a better speaker for that little money.
Nonetheless, if you *must* purchase new, I have read *many* glowing reviews of the Fostex active speakers. Here is a link to get you started:

Keep in mind that having "active" speakers means that you do not need a power amp, you can simply connect your source directly to the speaker inputs. The speakers referenced in the link above are only $399 brand new...
