Checking ebay, amazon and a few other locations I could not find any Stab HH90 motors to replace my SG-2100. Some were available at extreme prices, but I didn't recognize the vendors. Found and ordered the Sat Power SP120 from Casey at Hypermegasat site. The price was reasonable with shipping included.

Finished installing it yesterday and would like to say thank you to Hyper for stocking it in the U.S.

The install was easy since it's a SG-2100 knock off motor. The SP120 motor bracket is the same as the SG-2100, so the latitude and elevation markings match. Just unbolted old motor and bolted new motor to old bracket. Attached 90 cm dish to motor and Done!

Only thing different are the u-bolts seem to be a smaller size than original SG-2100. I was careful not to drop the motor since the body seems to be made from pot metal. Motor works, happy camper....

Again, since inventories seem to be getting low, I ordered another Geosat Pro 90 cm dish. This time from Rick's. Thanks Rick!

Hope the future improves for everyone!
