turning rotors

For disc brakes do you want a dial indicator with a vise-grip and a flex arm, or a magnetic base with fixed arms?
Some cars are easier on rotors than others. On the Camry, the rotors were turned and we didn't have any issues with them. On my Max, they warped after a few thousand miles. With AAP discounts, new rotors are rather reasonably priced. I think mine were ~$30/ rotor.
The other issue is finding someone who could turn them for a reasonable price. The last time I checked, the shop around the corner was charging $15/ rotor. Would rather pay the difference for new ones.
And most of the time when I'm working on my car, I don't have the others at home to use while the one I'm working on are on stands.

I no longer turn rotors, I just use them till they are super thin and put new ones on.
The only time I have "warp" rotors are when the initial quality is bad (bad cast, bad runout, etc), and it came back even after I turn it.

At the end of the flex arm is a magnet or vise grip?

I am finding it more difficult to find a shop that will turn rotors anymore. I did find a shop to turn rotors and they want $18/rotor. Not too bad but, not great either!
