Ask YC: What is a good (and cheap) domain name registrar? 18 years ago
Careful with GoDaddy. One of our fairly innocuous link request emails (yeah I know, I know) got reported to Godaddy and they threatened to re-absorb our domain. Fortunately our sysadmin defused the issue. I can't recommend an alternative as we're still at GoDaddy because our higher-ups don't take domain asset management as seriously as they should.
Most of my personal stuff was registered through doteasy.com, and I have no complaints after 2+ years with them, though these sites typically do light duty, YMMV etc
