The Radio Shack and Channel Master rotors are physically about the same. In fact, I think they buy the rotor mechanism from the same manufacturer.
The only cheap rotor product I personally have ever had trouble with was the controller box with the Centronnix rotors, but they don't even make those any more.
A few years ago, there was a temporary rotor supply problem because of some problem the consumer rotors were having and their manufacture was temporarily suspended, but I have heard no complaints since then.
The only time someone might have a problem with residential-grade rotors is if they develop a significant strain on the rotor, which can happen with multiple antennas or antennas with reflector screens (Channel Master 4221, 4228), but ordinarily, if you cut the mast piece that the antenna is mounted to short (typically, 2 feet or less, you shouldn't have a problem.
If you have to make it much longer because of the vertical span of your antenna array, you can buy a thrust bearing for, I think, around $40 that will solve the leverage problem.
The "better choice" rotor in the furnished link costs over $1,200. I'd move to another house in another market where I wouldn't need such an antenna before I'd pay $1,200 for an antenna rotor.
