I have a couple of posters that I'd like to get framed to keep them in good condition (and to look better of course). One is an actual movie poster, the other is just the same size as one (27x40). I don't want to pay too much for frames (really can't afford much either), but I don't want total crap ones either. Wanting something with a minimalistic appearance. What are some good places to look and what kind of prices should I expect?
