I do most of my shooting with a Leica (M240). Next in line is my Canon 5D. It has worked flawlessly for 10 years and the IQ is still amazing even for such old technology. Never had any desire to upgrade. If and when the 5D dies I'll look for a used MKII or III. I also have a Rebel XSi with the 18-55 IS kit zoom which I take with me to visit the grandkiddy. I do have a micro 4/3, a Sony, but I don't care for EVF's and would never use it in place of a DSLR.
