I'm with pamike, keep your eye on the classifieds. You can get almost any bow used in your price range. For new bows, your price range eliminates most of the "premier" customs. Plenty of good new bows available for less than $700 but it sounds like you are looking for something a little special.
My favorite recurves are Blacktail, Schafer Silvertip, Dale Dye, Robertson, and Wes Wallace but there are several I have not tried. Lots of nice bows out there, the ones I listed I have either bought used and kept or bought used, kept, and then ordered another new one built to my specs.
