Just got my polaroid spectra1200si, been playing with it for a while, but not really all that keen about the quality of spectra or 1200 film... anyone been trying any other instant cameras, for eg. the fuji-instax series? Also, been wondering which cameras the fuji FP-1000 series instant films (found in ruby, CP etc.) can be used with? I'm really keen on finding a black&white instant film, and polaroid doesn't carry any in the spectra range...
