Ok. How was their reiliability and which option would you take?
Alrighty then…
My first M8 died (shutter fault) in Iraq on the very mission I took it. The replacement M8 was an absolute tank and never failed me. To this day I regret selling it to upgrade to the M9. Consider it the "1 in 5" camera that held much value.
The first M9 had to be replaced due to multiple dead rows of pixels.
Second M9 was okay but it needed to be remapped while I was in Afghanistan (an expensive mess that cost me months of shooting). Because of this I bought a second body, the M9-P. The logic was by having two bodies would somehow increase reliability. Well, that camera had quirks too. Depending on what SD card I had and which ISO I used, I never knew what it was going to do, e.g. color banding, random stripes, half frames, etc. And I won't even begin on the firmware issues!
And during my lovely ownership of all three M9's, I've had to replace batteries (not to mention countless battery issues within the camera) and two complete chargers! While none of the M9's failed me outright, they nickel-dimed me to the point I could not consider them reliable.
Tallying the total amount of time I was waiting on a replacement camera, part or repair and it adds up to an entire YEAR!
One of the positive notes about this experience was my Leica dealer, Camera West, was always going out on the limb to make things right. On that side of the house Leica did good.
I love the M9 output but hated the worry and fear of carrying one around. NEVER in my life have I felt that way with any of my film M's. For me this outweighed the positive aspects of owning a digital Leica. Until they get this right the extra time and effort with film is worth it.
