I have a tool that might be useful for anyone buying expiring domains from GoDaddy, NameJet, SnapNames, or Pending Delete Names.

http://genericdomainfinder.com/savedsearches

You can enter the search criteria of names you're looking for, and save the search. Then, each day around 2am EST, you'll get mailed a list of any matching names expiring within the next 24 hours.

I put this together because I was tired of running the same searches every day on 4 different databases. Hope this can be useful for someone out there.

Fyi, it's a completely free service - though you need to create an account, so the system knows where to send the email to.
