Hello Ive been searching around for Apple watches in Craigslist and I've spotted a stainless steel 42mm with black sports band for $450. It seems to be a good price. Could probably negotiate with him. I've always thought of getting the sport since they both have exact same internals. I've seen Apple watch sport 42mm space greys on Craigslist for 350 or less. Is that a good price. The only pro to me for the ss is the sapphire screen. I've seen sports getting scratched up on YouTube. Do you think it's a good price for a used one?
