I was scouting around that other site for darkroom material, and while looking for developing tanks, I saw a thing called a contact printer. Looks like a little light box in which to put paper and the negs in. I suppose some people here have had some experience with those things, because I was wondering if it was worth finding one to make my own contact proof sheets at home. I am shooting only rollfilm for now (135 & 120), I am not even up to the point of having a tank and soup ready, but I like some planning. Is it worth investing in this? I don't need extra high quality, I just want positives of my shots that I could develop in the bathroom for quick examination, and I can't afford/don't have the space for an enlarger and a real darkroom. I read somewhere that Edward Weston did his contacts prints with a glass plate and a lightbulb, so how much does one really need for my purpose?
