My choice would be either the PST61, (I have one of the old ones) or the 
AlphaSpid although I believe there several other good rotators that use 
double worm gear drives or planetary gears. I do not like any rotator 
that used a wedge brake.   The early PST-61s had a physical design 
problem that allowed water to collect on the top seal which then caused 
the shaft to rust which then wore out the seal which then let water in 
which then caused the top bearing to go to pieces.  At least the 
bearings weren't expensive as the are the wheel bearings for compact 
cars. I understand the new model has protection for that top seal.

I'd rather overspend some than under spend even a little.
With the AlphaSpid or the PSt61 you don't have to worry about operating 
on windy days.  If it get *that windy* you better have your insurance 
paid up. <:-))
You do have to be concerned about fit with the PST61.  It's large and 
heavy.  (which is good) but you may have a problem getting it to fit in 
a 25G. I had to turn the motor 90 degrees so it's horizontal and sticks 
out the side of the 45G. The motor sticks out to the left side of the 
tower near the bottom of the photograph in
