Which lens? The Skopar is a fairly standard Tessar type; the Heliar can be ridiculously good (and seems to command prices to match).
Is there a set of holders with it? Those count---they're not so easy to find in good condition, and there are a lot of us with 9x12 cameras running around looking for extra filmholders. (Not me---I'm busy trying to identify the light leaks in the ones I've got.)
