If you keep your eyes open you MIGHT get a Lakland 5501 at the top of your budget or very slightly over. Best 5 string costing that kind of money that I've owned. The neck is just sublime.
Sire are great, but I'm not a great fan of their preamp. Also make sure you play before you buy as there are occasional QC issues (binding, etc) and some are like boat anchors (my Alder/Rosewood V7) was knocking on for 11lbs/5kg, although balance was good which helped a lot).
