I've had the Contax T (nice but I had trouble with it), Leica Mini-Lux (Gave up after 2 electronic fails), Mini III (just a Minolta but decent grab shot rig/still have and use it), Hi-Matic E (great lens/wonky functionality), Konica A4 (super lens/bad electronics). My easy favorite is the Konica S3. It's got a great GN flash system, quick focus, as good of a lens as far more expensive cameras. The lens mounting/housing isn't confidence inspiring but it's just the housing that floats around, it appears.
I sent one of these with a friend on a mountain pack-horse hunting trip. He also packed his Canon F-1 gear and Canon optics. His favorite darkroom prints from the trip were from the Konica and he promptly bought a pair of them for himself and made many fine images over the years.
