I've never had rotors resurfaced before...always just replaced 'em. Don't know what the cost for resurfacing is, but if it's about the same price as new rotors, I'd just get new rotors. New rotors are probably like $30-40 apiece for your car. Might as well do pads at that point, too, since your pads are "shaped" to whatever uneven surface your rotor has become, so it's nice to have fresh pads on fresh rotors.
