What to do if you get ripped off on eBay?

Well, an update (not much of one though):

The agreement we had was that I would overnight the check to him and I did. He got it last Saturday. He then said he would mail the goods on Monday at the latest and would contact me with a tracking number which I requested he do. Up to that last email he sent me after receiving the check we were in contact daily. I haven't heard from him since. Strike 1.

He has a 0 feedback rating. Yeah, I know I'm stupid for buying from someone with 0 feedback, but I took a chance and gave the guy the benefit of the doubt because I really wanted this item, and like any crook would, he sent me sincere sounding emails. Strike 2.

The package was supposed to be sent Monday with a tracking number sent to me. If it was sent Monday it would have easily been here by now, unless something happened in shipment (unlikely, but possible), and he never replied with any kind of tracking information, or even to tell me it shipped. I do a lot of buying and selling via UPS so I know what it takes to get a package from damn near anywhere in the U.S. Anyway, strike 3.

One good thing I have going for me is he didn't use a fictitious name, and appears to live at home with his parents.

I'll give him time before I start turning up the heat a little, but not much time. I may be acting a little hasty, but I want to get an early start in my search for solutions just in case. All signs so far are pointing to a scam.

Ian, thanks for the info. I'll check into seeing what these agencies can do for me if it turns out this guy is ripping me off.
