This is the case I got from Seidio:

No belt clip, but you can buy a holster that fits the case:

Kinda pricey but worth it. The case is really nice.
FYI I got this before:
Blue Rubber Hard Case for HTC Verizon/Sprint off ebay
by comparison the ebay case is HUGE, the sides just protrude out and make it hard to access the edges of the touch screen. It also weights more than the Seidio case.
Also the Seidio case has a smooth back (no bump where the cases off ebay have to attached a belt clip) so I can put the phone level on its back on my desk.
