Oh boy, one can can go on and on about this subject. Everyone's advise given so far is good. But I would tell you first off to go with your gut obviously. Even with eBay.
I have done several transactions through CL, buying and selling, everyone of them has been fine. A central location is good but I've visited with folks at their property, and I've had them come to mine. Only if in both cases we talked on the phone first. But if I get a response from someone whose spelling, punctuation, and overall grammar is that of a four year old I walk right away. Even if their selling and can't construct a paragraph, I'm not buying. And if they don't respond with a phone number I don't think their serious at all. Click on the link that brendodendo has in his post above. Read that. I would have been done with them from the first response. Now a typo or so ya, we're all guilty of that. I'm no English scholar but reading, "im wantin you lawn mowr. what the lowest price", makes me want to put the XDM up to their forehead.
And as it has been mentioned. Cash on the barrel head, and meeting in person, is the best. But... PayPal is a great tool. Don't deal with any checks or money orders what so ever. Checks are so 1980's, I can't even remember the last time I wrote a check. I've pushed up to 2K so far with a CL transaction using PayPal and all was good. I felt confident the whole time. Of course I talked with the chap on the phone a few times prior to sending money. If they say they don't have a PP account, well they don't need one to move money, that's not a legitimate excuse.
Back to the gut thing... Works every time. You'll know when you have a serious legitimate buyer with money.
