Hey guys i'm looking for a fully manual 35 mm camera for a photography class. I need something usable, reliable and preferably under $100. I am fully willing to go used and I've got some lenses that fit the Pentax K-mount system (off an old camera of my dads that i can't use for the class because its not full manual). I've heard good things about the Pentax K1000. Anyone recommend this camera or something that is better but won't cost more than my freaking car?
