Polaroid films (and camera) - Where to find?
 

Hello everyone!
My subject (and problem) is Polaroid-related.
I'm a photography student in University of Athens. As my diplomatic project I chose to work with Polaroid instant pictures... I have never worked with tha type of film-camera and I find it very unique... Problem is, that I can't find film (in resonable prices and without worrying if it's expired) for older models.
I found through Polaroid site, film for their newest model "300 instant camera", but nothing for older ones.
I'm not specific about the models(since I'm still looking for a camera to buy or borrow) but I would like to know if there is a seller or a site, or someone that could help me in search or film (and maybe camera).
By the way, I'm from Greece, so I'm worried that most seller won't send anything here... :(

Thanks a lot for any help!
Maria

PS. Any suggestions, are welcomed, cause as I said before I'm totally new to Polaroid world!
