If you can find a Geosat 1.2m - get it
Next I'd look for a Winegard or Fortec 1.2m
I have a Fortec 1.2 and have been very satisfied with it
If you can find an old Star Choice 1.0m - consider it - they are Winegard and are quite good
All of these can be motorized. If you get a STAB HH120 motor - you'll be good to go.
