If you're not stuck on the Polaroid brand, you can always get the modern Fuji Instax. http://www.amazon.com/Fujifilm-INSTAX-210-Instant-Camera/dp/B002NUP0D2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1350503505&sr=1-1&keywords=instax+wide+210

I have a couple of old Polaroid cameras but use the Fuji on gigs so I don't have to think about whether a 50-year-old piece of plastic will crumble.
