I just wish my Ricoh cameras were more reliable. All have developed faults sooner than I would like. My first Ricoh GXR body bricked itself one day. It just wouldn't power up. GRD III lens block malfunctioned and had to be replaced, and is starting to play up again. GR shutter now gets stuck when the camera turns on.
If I was a going on a trip, I'd definitely take a backup if the GR was the main camera. At this time, it would be a Panasonic LX10 for the extra wide angle, zoom, and superb video.
