Of the commonly available rotators, one of K7NV's rebuilt prop pitch
units is probably the most durable for heavy loads.
In my opinion, next would probably be the ProSisTel PST-71D (which I
have), but it weighs almost 90 pounds.
The ProSisTel PST-61D is generally considered similar to the Orion
2800. I still have one with stripped gears (antennas are OB16-3 and
OB2-40), but I get horrendous whirling winds here, and when they hit the
tower head on the torque forces on the boom ADD instead of balance.
That's a tough task for any rotator, but so far the 71D has held up.
I guarantee you won't break the mounting bracket on the ProSisTel units,
but you'd be wise to buy (or make your own like I did) something like
this for a mast clamp since the ProSisTel clamp is a poor design:

or this one, which I believe is made by K7NV:

The Yaesu 2800 and Orion 2800 have been suggested. I heard that you
have to be careful with the Yaesu and the mounting bracket as you can
break it. I have a Green Heron Controller.
It has also been suggested to get the NV or LXC mounting brackets for
the Orion.
Any other thoughts?
