If it is in nice shape, it is a good price compared to their going prices, but still is not "extremely cheap" for what you get. What you get with the 600SE is a dedicated Polaroid (or Fujiroid) camera with a dedicated lens mount that can only use two (perhaps three) lenses. There are also Mamiya Universals, on which the 600SE's are based, and which can be used with a Polaroid back or a film back. They are more versatile and cheaper. I would recommend one over a 600SE any day. I, for one, have never understood why 600Se's are so valuable, considering that Universals can do everything they can do, plus a lot more.
