I just wanted to post that video so you guys would see what a shop should do to check for a runout problem. No shop should just throw new rotors on a car without doing a couple of checks.
I haven't resurfaced a rotor on any of my personal vehicles for 20+ years. This is for a couple of reasons.

If the rotor developed a thickness variation to begin with, it happened for a reason (low quality materials, excessive heat build-up, etc). If you remove material from the rotor to make it smooth again, you also just made it thinner. So now its ability to handle heat has been reduced even further. The likelihood of the problem returning is high.
Rotors aren't expensive and I don't like doing a job more than once. So when my car needs rotors, I just replace them with high quality aftermarket. I've had good luck with rotors from brakeperformance.com. If someone is on a budget and money is tight, go ahead and resurface them.
When you install new rotors/pads, that is a good idea. If you have existing brakes, then trying to re-bed the pads to fix a pulsating brake pedal or shaking steering wheel is not going to fix the problem.
What do you think about rebedding the rotors?
Here is one issue I didn't think about which could be a problem for cars that are parked for a long time...
