And keep an eye on him to make sure he doesn't do anything with it until you have received payment in full. If he does try to use it before sending payment then follow up with options 3 & 4.

In my opinion, if you get "sue happy" it will scare away a lot of potential customers. Just speaking as a neutral 3rd party.
