I bought a Dark Blue one of these on ebay for $32.
Seidio Innocase Case & Holster for Samsung Epic 4 Blue
Came with a Belt Clip/Holster that has a soft fabric on the inside. Put it on yesterday and so far I'm Very Impressed!
Wasn't a fan of cases,but after I dropped my phone last week and put a few chips in the side chrome I thought I'd try one out. Just couldn't bring myself to pay $50 from Seido directly.
