Greg,

In terms of brute strength, quality of worksmanship, and dedicated 
customer support from Wyatt Lyzenga and colleagues in Fresno, I 
don't think you can beat the M^2 Orion OR2800 PDC rotator based on 
my experience with one swinging a KLM 40M3, KLM KT34XA, and 
KLM 2M13 in Northern California winds.  Appears it could turn a 
house without breaking a sweat, as I have siad before, and great 
attention from the folks at M^2.
