The only thing I hate about Craigslist is all the scammers contact you or everyone want to offer you nothing thinking your hard up for money. Have had better luck with the classifieds here and digitsmith. I quit posting on Craigslist due to the 50 emails wanting you to ship or they have a check for $1000 extra wanting you to cash it and split the difference which is a scam.
A new craigslist scam is to rent someone's house. I have a scanner and its happened here at least 12 times in the past few weeks. People show up to move into a owner occupied house. One guy even looked at the house with the scammer but said he couldn't show the house inside due to the current tenants request.
I have sold some stuff on Craigslist but using the forums specifically for printing or equipment sales has produced the best leads
