Without knowing you room/system etc I would suggest looking for used speakers in that price range. If your dead set on buying new check out Tekton.
There is a pair of Proac response 2.5 on another site that is just a hair over your budget with a very small blemish, I would strongly consider those as well as the Triangle Celius 202 listed on the same site.
