You got burned on the price... the One600 was the last of the basic Polaroid 600 cameras. SX-70's like the one posted in
>>3031939 were some of the best instant cameras ever made, however. The optics are better and it folds down to about 2" high.
Impossible Project for film. For what you have, you want film for 600 cameras... would go with BW for your first pack since you're new to TIP film, then move onto color when you're ready. It's expensive and don't expect Polaroid-level development times for color. Get it from B&H, at least there the shipping is free.
Instant film is daylight balanced... shoot in bright sun for best colors. I disagree wholeheartedly with
>>3031354, the Instax film in general seems too stale for my likings, but that may be largely due to the shitty limited-control cameras. Pic related was an Impossible SX-70 shot. In the right light the colors are fantastic.
