Personally, I would stick to paper for paper when it comes to Craigslist. At least when buying from individuals...I did buy some tickets for a game at OPACY from a broker off of CL, and IIRC they used a secure transaction service (and I used a specific credit card that I reserve for high-risk transactions like shopping in Hanoi or Lagos...or buying tickets from someone in Balmer).
How do you actually exchange the tickets on Craiglist? PDFs and Paypall? I have always been a bit skeptical unless something is actually being exchanged in person give the free form nature of the site.
