If you can afford it, get all new parts for anything that will see AC refrigerant; especially the compressor. The single most expensive part is the compressor and any dirt leftover in used parts can kill it. Rebuilt units generally don't last long either. If cost is a problem, I'd sooner get a used compressor than a rebuilt one (provided it was dirt cheap). I actually ran a used $50 compressor for many years before replacing everything with new parts.
