If you can't get your ideal name, think about adding words onto it and coming up with some variation.

Many web properties started with less than ideal domain names, ending up with what they wanted in the end.

Facebook - thefacebook.com Dropbox - getdropbox.com Delicious - del.icio.us Twitter - twittr.com

I'd suggest a tool like http://www.bustaname.com would help you out getting what you want.

I recently did this very same thing with a domain and got something incredibly close to what I originally wanted.
