AC on 2006

AC was a little weak this summer, and i decided to do a recharge kit. The kit didn't work out. Originally, I thought there was a blow out on condenser while trying to bring system up to pressure. AI swore this is the sole case and issue. I took to shop for inspection. Oil had blown out the escape valve of the compressor with no evidence of a leak on condenser. Shop originally wanted $2100 AC compressor kit installed. They want to replace compressor and condenser flush lines and charge it back up. The best price was a rebuilt compressor and new condenser installed 1500. I know you guys know how clunky AI is for auto repairs but its all I got so better than nothing.

AI is doubling down on condenser and says to replace it only and thinks my compressor is still good, Suggest replace expansion valve. I don't really think the shop is doing anything wrong but its all about doing work that they can put their one year warranty on. I can't diy on this one i don't have the space or facilities nor the vacuumed equipment. So the repair has to be a one shot deal to keep cost reasonable. I read through the other comments and i see your mostly recommending used compressors at that which i found interesting. So how would you go about this repair? As always thanks for your time in advance.
