So, I'm looking to upgrade from two sheets of plexiglass held together with clamps.
Looking for an 8x10 Bostick and Sullivan contact printing frame. I'm not sure how much these guys go for used, but I'd be willing to start haggling at $50 plus shipping.
Keep an eye out, they turn up on eBAy from time to time. I was just in their shop on Friday and they had some 8X10 frames which go for about $160if my memory serves me. Until you find what you need, you might take a look ast this one on ebay. 261528598578. $40 including shipping.
