Yes, there are tons of scammers lately on Pinside. Most are pretty obvious, but some are getting sneaky. Had multiple phone calls this past week on a machine I had listed...one wanted to buy right away and pay via Paypal and have someone else pick it up (scam, also called from private # and wouldn't give me his number)...two saw my machine elsewhere (same pics) for thousands less and thought it was legit but managed to get ahold of me before sending money to the scammer.
Remember guys...if it sounds too good to be true, it probably is!
