Having used the CL but not the CLE I tend to think that the later camera by Minolta (who built both, anyways) might be the better choice for the various reasons stated above. Cosina-Voigtlander makes more recent 40mm lens compatible rangefinders that may interest you and you can always fit the Summicron f2 to them if you don't like the C-V lens line. Probably none of these have the build quality or smoothness of the M bodies if that is a concern.
