HESITANT with NEW member sellers

I seem to struggle too frequently with members who are NEW, no history at all, but who seem to have beautiful systems, excellent taste, and are offering very reasonable deal on a very high end piece of audio equipment. 
I have passed up on "mint" Thiel speakers and "mint" REF6 Audio Research due to my fear of being ripped off. 
Is there protection built into AUDIOGON? Has anyone had experience with that?
I prefer Pay Pal, in hopes that they would provide protection...I believe they do..but the same sellers want cash or check....I am HESITANT.
