I made a proofer so I could proof 6x7(10 frames per roll of 120) onto 11x14(or 10"x12" cut from 12" roll paper<ebay>). had some scrap plywood, sanded it, got some 1/4" glass cut at my glazier, got some felt-backed foam from the craft store, glued the foam to the board, and made a duct tape hinge to hold the glass. Total cost: about $28, not including time(about 1hr total to put it all together) to get the wood to size. I had the glass cut to 11.5x16, so there's a little bit of overhang. So now I can proof my 36 exposure rolls(6negs x 6 strips), onto the 10x12, same as the 6x7 and 645. thought about using the starfire glass(less green cast, less lead content), but with the extreme price difference, I leaned to standard 1/4" plate. and I can't see a color difference filter pack-wise from proof sheets to final prints.

works for me, you might want to try building one yourself, it can be very rewarding

I'm acutally in the process of making some for some of my classmates, albeit, charging $50 for them, nice little side business .
