I need to replace my front brake pads.. I called the dealership and they wanted $325 for replacing and surfacing the disc. $120(Is this overpriced?) for the pads itself.

I don't want to pay those prices.
what are some good front brake pads(oem is okay too) I can buy for my car(model number?)?
I think I'll rather purchase my own pads and have them installed at a shop and pay labor cuz I think the shops usually use generic cheap craps.

Where can I get them? I live in Los Angeles... online is fine too.
