[Towertalk] Rotator recommendation

[David]

I'm going to replace my current rotor with something a bit more substantial.
The rotor will need to fit inside the top section of my new HDX-555 tower
(inside dimension is 12").   I'll be turning an Optibeam OB11-3 and either a
40mtr rotatable dipole or a small WARC antenna stacked above it on a 20'
mast.

I'd like to stay in the $1000 range if possible.

Any happy campers out there with a rotor you'd like to recommend?

Thanks to all,
David, K4ZZR
