I have bought tickets from eBay for two different trips... both times, the transaction turned out okay... however, I was paranoid both times until the ticket slid through the machine and the gate was open for us to enter. Then, you are paranoid, wondering if it will work the next day at the next park! I bought tickets from "individuals" - by that I mean it was a Disney fan who returned from their trip and some days left over and decided to sell the ticket - not a seller who had tons of different tickets for sale. I kept all of the correspondence I had with the sellers and made sure I had phone numbers, etc. I told the seller upfront I was leary and was going the CYA route - the sellers I dealt with were very upfront and provided the information I requested. I also made sure that we had access to funds in the event the tickets were no good so another set could be purchased. I had a good experience, but don't trust my luck for a third try!
