For one, the M10 is not the best example of a Cherry blue 'board, from what I understand, due to quality issues, and listening to the soundclips of the Das vs. the M10, they sound completely different. You may want to give the Das a try (if you know someone with one) before giving up on the blue Cherries. I almost gave up on the black Alps before getting a few NIB kbs with them, now they are my favorite switches. I would imagine you would like the Cherry browns if you don't care for the clicking. You may also like the Alps blacks; the Dell/SGI AT-101W are plentiful and cheap to try. I would try to get an NIB one, if you can. The first Dell I got had some dirty switches which created an odd friction in the keys. My NIB ones have been absolutely fantastic, though.
