Following up on what sneakypete said. Be prepared that the place you take the rotors to for resurfacing will measure their thickness and may determine that the rotors are too thin to resurface. If so, you may find yourself in a spot where you will feel forced to buy not one but a pair of rotors since they should normally be replaced in pairs. To avoid getting caught with your pants down, I suggest you measure your rotors with a caliper or, if not available, a metric scale and compare the thickness to the TSRM specs prior to going to the resurfacer.
Also, my experince with cheap part store OEM rotors has not been that good. They are prone to warping and brake fade if you drive hard. I would suggest for your daily driver OEM rotors from Brembo, which are available for $50 each from TireRack:
