Just looking for some advice: I was on another FP board and was offered a beaten up Waterman 52 with a nib transplant with a super nice 0.23 to about 3mm flex nib on it. Dude seemed pretty nice and genuine, so I went ahead via paypal. He posted images of the pen and even did a writing sample for me. He confirmed he got my payment on the 17th (16th in the US) and said he'd clean it and send it the day after (and send me tracking number / attach it to the paypal payment, which he still hasn't done either). Since then, he hasn't responded to any PM's and he's showing the 20th as his last "activity" even though he didn't post anything. His last post was his PM to me saying he'd send it tomorrow, I believe. I even sent an email off to the address used for his paypal hoping that would connect. My question: How long do you think is reasonable (assuming no correspondence) before I start mentioning forcing a refund from paypal / actually go ahead with it. I'm thinking one and a half weeks, charging back on the 2nd week, but curious to get some input from other people with more experience in the buying / selling pen market.
