Someone posted http://domainlagoon.com/ a couple days ago. I tried it with an alternate e-mail and it works, don't have to buy anything or have a CC or anything of the sort. Gives you a free domain for 1 year from http://dietzel1.com/. Just use an alternate e-mail, otherwise you'll get "offers" in your inbox.
All I had to do was complete a few "offers" which is basically randomly filling out a few surveys and wait for them to be approved. Approval took a couple hours, then I registered the domain, and the next day it was activated.
I don't know if it's good or not yet, though, but it's free.
