Zeiss has a rangefinder, but it's not digital. Some folks are betting on them to release a digital rangefinder (via Cosina, same people who make the Voigtlander rangefinders and lenses), but my money's on Nikon. There have been some juicy rumors about DRF vanity projects at Nikon that might actually make it onto the market someday.
I skipped getting a pre-M Leica because of the squinty viewfinder. I love my M2, though the older Leicas have a different kind of charm, and are smaller to boot.
