    Well, I'd say there's some of that but as far as US rotators go they have 
their own set of weaknesses. The CDE/Hy-Gain/MFJ rotators were designed in 
the sixties and their problems are well documented; i.e. indicator pot, weak 
ring gear, sticky brake, etc. 

    Designing an electrical/mechanical contrivance to do what we expect a 
rotator to do is challenging. In this new millenium we're likey to see two 
new rotators that I'm aware of. Craig at CATS unveiled his at Dayton; it's a 
worm gear drive which is the way to go and is supposed to be in the $600 
range. Whether it (or the other one that seems to be similar in design and 
execution) makes it to market or not is yet to be seen.
