You might want to look into Sprint springs. They are pretty good springs and are around your price range. The two brands you might want to stay away from are Arospeed and APC. I have never delt with these APC or Arospeed but I hear they make some bad products.

Actually there is a group buy on some Neuspeed springs http://www.redlineautosport.com/v2.0/groupbuy.php and they are only 137.00$ shipped on either race or sport springs.
