My little sister is going to be taking a Black and White Photography class at college and it requires a film SLR. Money is a bit of an issue as she is a college student and I'd rather not lend her my N75. I was looking at the Vivitar models which seem to be a great bang for the buck, but I have been told that I can get some older cameras for much cheaper. I was looking at some Ricoh/Sears models on eBay as well as some Pentax models. Idealy, it should have a meter but be full manual. Any suggestions?
