Uh, no. You can get them turned for $10-15 each. You aren't going to get new ones for that, though most rotors can only be turned once. I highly recommend either turning them or replacing them with every pad replacement. All I can say about those of you that say it's OK to sand them lightly is maybe you don't care much about the long-term, or maybe you aren't as particular as I am. I have never paid for a brake job and have done the brakes on all my cars, including several with drum brakes. Additionally, I have had several long term cars, seven, eight, and even two cars eleven years, and one 16 years. My experience says that pads break in better and last longer when you take care with your rotors. Why would you go to the trouble of replacing your pads with Hawks, only to have them have issues after 10k miles because of uneven rotor wear?
Do the right thing; turn or replace your rotors when you replace your pads.
Under no circumstances do you resurface rotors, unless you have a run-out that is beyond spec. You've been tickled and blown into your ear for far too long. Thats cute that you have so many long term cars, but your knowledge is dated.
Do you believe too that Rotors warp? They really don't.
Pads usually leave an even deposit on the rotor, that when swapping just pads, you should remove that deposit, and let the new pads re-deposit a new layer, also called "bedding in rotors." This process makes braking smoother and improves braking performance. Thus, the recommendation to just sand/scuff the old rotor to remove the old pad deposits when possible.
Rotors only need two things. Be within minimum thickness, of which is when you actually replace them; and/or have an even run-out, of which perhaps you investigate re-surfacing, but as long as the first condition isn't met upon removing material. They don't warp, and certainly don't need to be replaced as you change pads each time.
So the proper recommendation is, meet minimum rotor thickness per OE spec.
If you have the means, measure run-out. (Not terribly important in many cases, and most don't have the means to do it properly anyways)
Replace pads only if your budget constrained, and the rotors meet minimum thickness. Sand to scuff and remove old pad material
Perform a proper bedding procedure, or drive easy with no hard stops for 500 miles.
