Get a Timken or AcDelco, don't waste your time with the cheap shit at Advanced or Autozone. Trust me the wheel bearings may not last long to begin with, but you'll typically get more life out those two brands.
Install usually isn't horrible on those cars, even rusted they can be removed without excessive beating. The price is even a little high for a dealership, the hub is likely almost $400 (dealership price, cheaper elsewhere) and labor should only be about 1.2 hours, putting you around $550. It can be done cheaper obviously.
