From what I understand, Godaddy does nothing more than Namecheap besides advertise (which makes them pass that cost onto consumers). I'm not tremendously well versed though. Also, I like .me domains for personal use, but that's just preference.
It doesn't sound like you need a host, just a domain for your own server, but if you did, I recommend Webfaction without reserve. It's absolutely awesome. (It's not free, but if you're afraid to spend the money, I think they give you 30 days with which you can get a full refund, no questions asked.)
