Probably equally painless, I'm setting the DSLR's aside, for a while, and buying old Russian film cameras and getting the results scanned at Costco. Gives me the RD1 digital experience but with a true rangefinder and a trip back in time with film, though today's film is so so good.
I can't rationalize your step from SLR to rangefinder, though. That is just too big a step. But you are having fun so you are leading the pack, in my mind.
