i30 a/c compressor

A/c compressor is making a very loud noise and needs to be replaced on 2001 i30 with 149k miles. 2 questions:
1) What is recommended: buy old from junkyard (100 days warranty) or new remanufactured four seasons from autozone for $300 (3 months warranty)

2) Is there anything else we should replace when changing compressor.

1) Longer warranty ? ... I guess no big difference, depend$.

2) All belts

3) If alt is original, hi time to swap.

Your compressor clutch bearing may be faulty, if you have noise from AC compressor. So replace it when you change the compressor.
