Seido is $49.99 for 83xx series. I found a place called MobileCityOnline selling the exact same combo for $39. I bought one and it's awesome to say the least.

Worried about screen protection? Me too, so I took a piece of transparency film, cut to size, and the pressure of snapping together the two skin pieces holds it in place very securely.

The other added bonus I found is that Seido also included a concealed magnet for entering sleep mode in either screen in or screen out while in the holster.
