Gandi is the best domain registrar by far. I've been using Gandi for years, and I have never once had an issue with them. Gand is fast and affordable.

Their support is excellent, and their UI beats any other registrars UI that I've used by far. It's simple, sleek, fast, and effective. A solid UI is important for anyone that has to work with domains frequently.

While I don't use these features, they also provide webmail and blogs for free with your domain.

I can't recommend Gandi enough.
