The Polaroid 250 is currently the only Polaroid in my collection, and will probably be the only one as it is hard to beat. The 250 was a high end model that originally retailed for around $160 and was produced from around 1967-1969. It uses peel-apart pack-film, which is still produced by Fuji (since Polaroid itself is no longer around). The 250 (and later high end folding models) comes with a high quality, coupled, single window rangefinder designed by Zeiss. It also comes with a high quality three-element glass lens that produces fairly sharp pictures. Unlike the similar, but cheaper models produced around the same time, the 250 is solidly built with a metal frame. It produces prints that are 3.25"x 4.25". The only downside to the camera is that it takes an unusual battery that you generally can't find in stores, but is easy to find online. I have converted mine to take normal AAA batteries instead which makes thinks a little easier.
