I couldn't find a thread about Luigi's half-case for the X100 so I thought I'd make one, if anyone is curious about it.
I'm very happy with the X100 but I really wanted a better grip, so I started looking around and found Luigi's "basic plus" half-case with built-in grip + strap.
I normally never use cases with my cameras but I'm loving it with this one. Apart from the much improved grip I really like the hanging rear door. Not only does it disguise the fact that I'm carrying around an expensive digital camera (several people have thought it was some old thing from the 70s) - it also makes me chimp less
(I find the 1.5 second review in the finder really useful)
Never thought I'd pay that much for a case but in this case (hah..) I feel it's worth it... strap is nice too!
(Also added filter adapter+hood+UV filter - US seller rainbowimaging on eBay (no connection) sells the combination for $24)
