Talk it over with Jeff at Badger; he's a straight shooter. Also, I'd track down one of the RB-67 power drive 6x8 backs. Really good film flatness and a convenient 9 frames per roll that fit in a single negative storage page.
This camera looks interesting, and certainly affordable. Do you or anyone have experience with this camera? My fear with cheap wooden 4x5s is always flimsiness.
