JB Camera Designs half case
I bought one of JB Camera designs half cases for my X10 and I give it a big thumbs up. It's a plastic material that comes in a few colors (I got black). It has a nice firm, but grippy, texture and comes with a stainless screw that threads into the tripod socket. The finish is very good and, in the case of the black, looks like an OEM piece. It definitely adds to the handling of the camera and the fit on the camera is very good. JB was very helpful and a pleasure to deal with. Highly recommended if you're looking for a functional half case. The protection to the bottom is excellent and the little LCD "bumper" is a nice touch. Grade A product.
