I'm taking an intermediate photography class this semster at school, and I learned this evening that I will need a medium format camera. I have a pretty decent 35mm SLR, but I am sans medium. I'm not exactly rolling in money, but I do not want to have to drop this class because of a lack of proper equipment. Holga is not an option. What kind of recomendations do you all have to offer for an inexpensive camera that has decent quality?
