Two years ago, I found a bow on eBay that looked good for my wife. I asked for a picture of the sticker. It looked good. I got the bow. It arrived and it was IMMEDIATELY apparent to me that the cam had been changed and not only was the DL way too short but as a result, the #-age was off, too. I was going to return it but it did fit my smaller-then son, so we kept it as the price was acceptable and it was a good bow for him. My wife took his old Hoyt Ignite and everyone was reasonably happy. But the fact is, the bow was NOT as described and the owner was clueless.
My son grew and a month ago I started looking for a new used bow for him- had to be 40-50# and 26-28" DL which is kind of a hard find. I found about 10 candidates on eBay, the vast majority of which had no, or inaccurate, information on draw length or poundage but I was guessing they might be correct. I sent questions to all of those people. I got back 3 responses, 2 of which told me that the people had no clue what they were talking about (one guy quoted the Hoyt catalog and according to him, his Charger went from 30-80# DW and 24-30" DL. Oooookkkaayyyyy). Almost NONE of the photos show the good side of the cam- the side with all the numbers on it which will tell me a lot of good information. I asked one seller for a picture of the sticker on the limb with the information it. I got back something that was postage-stamp sized and totally unreadable. Etc. The majority of people never answered my simple questions.
Meanwhile, I found an appropriate bow on AT. I asked a question. I got a great and clearly knowledgeable answer, quickly. I asked another question, got another great answer, quickly. We discussed arrows. Etc. I bought that one. It arrived and it's perfect.
eBay sucks. AT, well.... doesn't quite rule.... but is WAY better. IMHEO
