Definitely nothing wrong with checking Craig's list. I've never used it to buy or sell so I don't have any experience with it. I was actually just trying to crack a joke which doesn't always work well in typing.

My preference for using ebay first for a used instrument lies in my past experience with it. Their reach is worldwide. I've even shipped one guitar to Japan and one to England.

Most music retailers don't stock many used instruments and even when they do their markup is outrageous so I prefer to buy directly from individuals.
