Film is not dead and a lot of here use it, but it is just not off the shelf available anymore. add to that where are you going to get it processed, and printed and you start to see that it is a nogo for the beginner. Most people I know that shoot film develop it themselves and most have darkroom/print setups. you have to have passion for film these days. (and money)
You did not say what she was using in school. That might influence what you get her, or what she wants in a camera. To me a camera is a tool, I am not married to a brand. For myself I use Nikon because I am cheap. I can buy a nikon film lens mad in the 70's from a yard sale, and it will go right in my latest model D4s and auto focus and meter light. I use Nikon at work because thats what they gave me.
KEH has been mentioned and is a great place for used gear. I have bought from them, and will again.
$200, yeah thats a tight price point for a DSLR but anything is possible if you look hard enough.
Hit craigslist. I have bought some good glass there and camera gear is relatively easy to check out on the spot. Pawn shops can work well too.
You will need the camera, lens, memory chip/card of some kind. Dont skimp on that. get the fastest pro grade chip you can even if it dosent hold too much. But there days a 32MB chip in prograde can be had for around $50. they were $150 when I last bought them two years ago. The reason is that your camera can only losd photos as fast as the chip will allow. A $200 camera probably wont over run a standard Walmart chip, bit for $50 go for the good stuff.
You will need a computer, you seem to have one already, you will need a card reader to pull the photos off of the chip and into the camera. a good card reader is $15-$20.
You will need some type of processing software to get the most out of the photos. This is the darkroom of the digital age. good photos are developed there.
Boy this went on longer than I intended. Good luck to her. Ga has some good photo opportunities.
