Who is the Best Registrar? (take 2)

cardozo asks: "Since my registrar recently did a bad customer service job with me, and their site wasn't all that easy to use, I'm in the market for a new registrar. Slashdot has responded to this question in the distant past, but the world has changed since Feb 2000!. Price is important, but customer service is too. Features are less important to me, but I can imagine that having email forwarding, etc. would be nice. So who do you think is the best registrar?"
