Zeiss seems to have positioned itself in a sensible part of the market between the entry-level (but reliable by my experience) Voigtlander Bessas, and the prestige price point of a new Leica. I'll admit I want a Zeiss Ikon, but my R2A gets the job done fine. I haven't had any issues, but I have a 2 year Australian warranty if anything comes up, so I'm not really worried.
I wouldn't turn down my nose up at the lens offerings from any of them.
