I also use godaddy.com as a domain registrar.
I'm mostly satisfied with them, but they have a tendency toward unethical business practices. I purchased their private registration service, and immediately afterwards changed the ownership on a domain. This had the effect of cancelling the private registration service, and I had to repurchase it, so in effect I paid 2x the fee for a single service. I exchanged several emails with them, but they refused to refund the extra fee.
