I just ordered a Chamonix 5X7 wet-plate holder - looks like a good design.
I agree about cleanliness but it's a lot cheaper for learning than one of Jody's probably-very-nice-but-certainly-very-expensive plate holders. Why is a larger groundglass than your plate a problem? I think it's nice to have a lookaround area around your frame.
