Hi people! I'm kinda stuck in choosing a polaroid as a gift. Just wondering, which would you choose? - polaroid one-step - polaroid one600 pro - sx-70 - polaroid pronto land sonar onestep Since i'm a digital user, i'm really new to these things. pls help me out? I was told by the seller that he prefers the sx-70 before of the blurred background, despite an iso of 160 only.
