I find that there are 2 types of people. Some who will only use eBay because they either don't want to interact in person with strange craigslist people, or are maybe scared, and those who use craigslist and just deal with people.
I've done both. For the most part, on eBay, between the eBay fees (even on shipping) and paypal fees, I rarely even break even. I might as well literally throw the thing in the trash. It would end up costing me less. I actually have 2 nvidia big dollar graphics cards I want to get rid of and will probably either put them on craigslist or scrap them. I expect that any eBay buyer is going to file a complaint that it doesn't work and with eBay always siding with the buyer, I've just given it away and lost the cost to ship it.
I've met craigslist people all over and never had an issue. To my house, all the time. At their house, many, many times. Heck....I bought a stratocaster in a Sunoco parking lot. I showed up with my battery belt held amp and cord to test it out, played it, made a lower offer that was accepted and bought myself a guitar. Out of the thousands of transactions, I can't think of a single time I was killed. I'm old and my memory isn't great, but I think I'd remember if that happened. But I do understand if you live in a bad area or something. Bring a friend? I guess that wouldn't work for me as I have no friends who would put up with going with me a few times every single week someplace.
