sounds expensive, sorry man.

as far as the AC, I had mine redone last summer, price was 1100 just for the compressor if I went with a new one. Somehow they found a remanufactured one for 600, it was about 900 when all the work and dryer, evaporator, etc. were all replaced. Still trying to pay that credit card off. . .
