If the dish is in decent condition, it's certainly worth $35 for an 8 or 10 foot mesh.
If you can use the feed & LNB that's a plus, but I would probably get a GeoSatPro C2 for C-band only.
If the motor works, great. If not, well... replacements aren't so expensive.
I'd run it with a Gbox if not on a 4DTV receiver.
Make sure you get enough of the pole so you don't need to jump through hoops planting it! -
