MF camera kit survey

[Alan Lewis <3-d@xxxxxxxx>]

Hi again people.

I've got a few survey questions:

If I were considering designing an entry level medium format stereo
camera kit to build (not that I am mind you....) that had the following
required features:

1) Focus by rotating element on lenses (using lenses from other cameras
of course).  IOW; no focus by shifting lenses.

2) Viewfinder, not third lens ground glass.

3) Single roll of film.

4) "Little red window" film advance.

What do you think about the following:

1) What lens to use?

2) Inexpensive way to get or design a viewfinder that people would
actually like, and might even work.

3) Other things to consider (remember, entry level camera, inexpensive
is the operative word).

4) Would anyone come to my party?

I appreciate all input.  Thanks.
