sorry Joe, i should elaborate. i've seen 3 d's go by on the us ebay in the last 7 months. i'm pretty sure one of them worked as it was a personal estate sale. regarding the s, s2 and s2a, they not in the same numbers as the hasselblad 500c but they are there. if you're prepared to wait and you know your stuff you should snap up a bargain. i bought an s2a with a nikkor 50mm/3.5 for around 150 dollars. at the moment there's an s2 with an iffy back going for 100 dollars. happy hunting.
