I have the dp2m and would really like to try the 3. Never seen any Merrill come through our photo shop in the last two years.
I'm getting a little tired of shooting my newer cameras and I think I'll get my dp2m out again.
A couple of years back I saw some large prints from each of the Merrills an each was superb including the dp1m you're considering Keith.
