Does anybody know this guy personally??

In february I tried to buy his greddy type s blow off valve for 100 dollars. He lives in cocoa beach, i didnt feel like driving down there so we decided to do this deal over the internet. He said that he will ship it as soon as he gets the money. I sent the money pay pal, towards the end of feb, i talked to him he said that he would look for the bov. 2 days later he said that he couldnt find it and that he would have to send my money back. I said that that was fine. He never sent the money. He then said that it takes 5 days or so for the money to go through pay pal.... I had never used pay pal b4 i had no reason to suspect the guy was scamming me. After 5 days when it didnt come through i talked to the guy he said hmm it didnt work hell try again and it will take 5 days or so. So now im starting to get suspicious. The guy said that if it oesnt go through this time hell just send a money order. Well long story short he never sent the damn money. If any of you know him and could get the money from him or the bov thatd be fine. I just want my 100 dollars back. He blocked my sn on AIM and I cant get ahold of him.
