You will need to go to the Amateur radio related sites to find them though.
Unfortunately Hy-Gain is run by MFJ now.

Several of the Yaesu rotors aren't bad also.
This G450 will handle up to 10 sq ft. of wind load.

At a typical hamfest a used Ham III or Ham IV would run you about $250 to $300 bucks. If you could find an AR40 or one of the smaller ones, they would likely be quite a bit less. The thing is the price of rotors has gone up a bunch in the last few years. The used ones many years old sell for about what they cost new back then. Of course all of the CDE rotors are rebuild-able. These rotors were originally designed to turn medium to large ham arrays, and have braking mechanisms and ball bearing races in them. But if you are talking about stacking large TV arrays, the wind load can add up to quite a bit, and you should consider these rotors. All of the smaller "tv" rotors have no brakes, and some even have nylon gearing. They ain't gonna last long.
Norms rotor service rebuilds rotors, but also has rotors for sale. (refurbs)
An old Ham II or Ham III would be fine for the largest of TV stacked arrays. Even an old HAM-M

If you need a lower mast bracket support I have a new one never used with my old Ham III
It has always been in a tower and never had need for the lower mast support bracket/clamp, hence it is new unused.
I would have to dig it out of a box up in the barn, but I would let you have it for less than Norm wants for one.
Give us a shout if you need more info.
