Why not add a reminder to your listing to save your as a "Favorite"?  Take advantage of every oppportunity to keep your name in front of your potential buyers.  eBay is adding "Favorite Searches" for Guests, too.  From eBay: 

In May we introduced My eBay for Guests, which allows people who have not yet registered on eBay to Watch items and be notified when they're about to end. We'll soon expand these Guest features to let unregistered users:

Save Favorite Searches [http://pages.ebay.com/My_eBay/favorites/?ssPageName=CMDV:AB] that they can view in My eBay for Guests.
Run these searches at specific intervals and have the results emailed to them.
