I'm not sure I'd pay $20, much less $160+ for that Viewsat 9000 HD.
The seller is getting out while it (-may-) still have a few cents value! -

Viewsats are not known for their FTA-friendliness.... like motor & switch control.
As for the Coolsat at $75, that's a joke, unless it's one of their HD models...
... and even then, I'd save my money for an AZbox...
