a while back I had the same piece meal type experience.
I put in a new compressor and drier, just to have the condenser fail within a few months.
I kept the system pressurized until I could replace the condenser.
Then I evac'd the system, quickly popped on the new condenser, and evac'd again, charged it up and all is cool.
as long as your system kept under pressure and is not open to the air for too long during the repair, then I'd chance it and not replace the new drier.
