I found this on Ebay. It's a 'PIECE SHARP ZAURUS - PARTIE EXT SUP SL-C1000', or the top half of the screens plastic shell from a C1000.
I think this and an all black Piel Frama case would make a bad PDA.
I was wondering if anyone knew any other suppliers of the plastic shell for a C1000? I would rather order it from Japan directly ...
