Get an M2 or M3 and you are set with the same pix for less money. Anything they've released since has been thoroughly unnecessary, and I do not understand the price differences on the used market. M6s and M7s are way overpriced and M2/M3 bodies are way underpriced. You might find it wise to concentrate more on what glass you want, and put it on a cheap body like a Voigtlander. That will also take care of your aversion to getting an old camera.
