I would recommend 7 days just in case the person is unavailable for a few days.
To avoid this in the future, set the expectation up for for payment. First, put in your auction description when you expect payment after end of auction- 7 days seems to reasonable since most pay well before that anyway. At Day 6 if there is no payment send reminder email, and than if not paid on Day 7 file NPB on Day 8. Stating your policy in your listing will help you down the line if there is ever an issue, the ebay people can pull up that info in a dispute.

Patience probably is a virtue here but I have been burned soooooooo many times by non-paying bidders that I understand where CC is coming from. In my experience it seems that if a bidder doesn't pay within 24 hours then he or she has no intention of ever paying. That's obviously a generalization but it happens quite a lot. Sometimes I'll even get an email several days after the auction has closed, saying, "I don't really want this. Can you cancel the transaction?" Then why bid? Why bid???
