I want to buy my son his first film camera. Seems like the Canon Scoopic M or MS would be good, although I believe they use Arriflex at his school. Scoopic seems to be reasonablly priced. I have a couple of questions. What should I expect to pay? What features should be included? (although they seem to not have many extras) What should I look for as possible scams? (Reading some of the posts has scared me a bit) :o Any advice would be appreciated. Thank you Sharon Hall
