Polaroid SX-70 Model 3
The model 3 was the only SX-70 that wasn't an SLR and it was also the least expensive SX-70. It still has the same black and tan 70s' styling and lens, but with scale focussing rather than a more accurate SLR split screen. It is still great for photo-manipulations and is easy to find in working condition for less than $20.
