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 released. It still has the same groovy back and tan 70's styling and lens but with scale focussing rather than a more accurate SLR split screen. Still great for photo-manipulations and easy to find in working condition for less than $20.
