I had this happen to me! On a vintage sewing machine. The ad reappeared no less than FOUR times! Everytime I emailed the seller expressing my interest (no phone was given) and never heard back. So I am thinking this was a case of someone who didn't have the slightest idea how to use Craigs list. I bet they never were able to sell their sewing machine because they didn't understand how to retreive their emails from CL. It is frustrating but I figure when I never heard back each time I responded to the ad it just wasn't meant to be.
