i just remembered, a good budget fan solution if you want to take the chance and go with a used part that you have no idea when it will fail will be dual 93-97 nissan altima fans.

with a little bit of trimming they will fit rather well, and have both low and high circuits on each fan. wire it all together and they move alot of air. A LOT of air. make sure you grab the relays to turn them on and off out of the altima as well.
