Hello I hope this is the right place to post

I´ve been looking at this P1 at **** (see:
http://cgi.****.com/ws/****ISAPI.dll...sid=p3907.m29), and I´m just not sure about this guy... He´s feedback is quite bad, but he sold a P2 successfully some months ago. I told him that his price was too high, and he changed it very quickly. He wants me to pay through paypal. I´m not a very experienced ****er and just wanted some second opinions

So please respond fast, it´s going in 1day and 1 hour.
And one more thing. If I buy it and end up not getting it, will paypal give me the money back? Thanks
