Hey I do the same too, but I have so many superb automatic aperture ( & some are automatic aperture only ) M42 lenses that it would be worth it for me to get a M42 DSLR body if somebody made one. I dont like fooling around with auto/manual switches, manual or preset lenses on a SLR to take photos if I dont have to, it's just to cumbersome and error prone to my liking.
