I just bought a remanufactured one through AutoZone for $28.99. Found it on their website and brought in the printout to my local store. The price in their computer was $37. Showed them the printout and got it for the $29 <img src="/forums/images/graemlins/kewl.gif" alt="" />.

The one of the pistons were frozen on mine as well. Rebuilding them is relatively cheap but I think spending the extra 20 bucks and saving the time it takes to rebuild em is well worth it.
