You might try a USAccoustics amp from www.crutchfield.com On paper they seem to be a decent amp and are not very expensive. I have never heard/used one though.
OK, if it's something cheap you want I can get you a Crunch amp for pretty cheap, and they are damn good amps for their price I had one pushing 2 12" Kicker Solobarics when my Alpine blew and it pounded. But let me know exactly what it is you want and i'll give you a price.
