You have a lot of choices in the price range you are looking. Have you looked at partsexpress with their line of kits they offer. They too have some kits with drivers from Usher that are pretty good sounding and they won't break the bank.
Have you also looked at the Magnepan MMG's? That is a wonderful speaker in your price range. And 40 watts will drive them well. They do have to come off the wall a bit which may be inconvenient in some rooms.
