B&W 802d Misleading Information and Scammers

Hello,
I am relatively new to this forum. About two months ago I decided after hearing some 802d speakers that I would invest in a pair. I read up everyday on different forums on this site and others about peoples opinions on these speakers but mainly about how to run them. I was convinced after so much talk that my 802d would not run on my Marantz sl7300 (100wpc) receiver. Anyways after setting them up just to test I was surprised that they still sounded very good, granted that I do have to turn it right up to get some substance out of it.
I am going to upgrade the cable and put a power amplifier in but I thought if there was anyone else out there in a similar situation to me that this information would be some peace of mind.
The other thing that I found was that when trying to purchase these speakers that almost everybody on ebay selling them was a scammer and for some reason unknown to me paypal is not a preferred method to be paid, where is the guarantee that you will get your goods?? Has anybody else had run ins with who they think were scammers?
