Randy - I've sold lots of things on Craigslist. The only way it works is if you only sell to local buyers. Test people in your reply to their ad by asking them where in town they live or could meet to see the product... if they can give you an even semi-legit response, you're on the right track.
If you get any inquiries that don't mention the product by name or show some level of knowledge about what is for sale, you've got yourself a scammer. (your note above fails this test)
Stay local and you will be fine. If you can't sell it locally, ebay is the way to go.
