Domain with numbers?

[zach]

and so moving on to Zach's tip of the year: Register names that people recognize, unless you can MAKE people recognize it yourself (by branding it). If you register a domain by substituting numbers for letters, and no one else uses that substitution, your domain will not be valuable (it won't found by people looking for it, it will be wrongly typed in, search engines won't return your result for a search without the number, etc.)
