Keep in mind GoDaddy's Terms, where they reserver the right to terminate your domains/account at any time, for any reason, without any notice. I would recommend never hosting a business or other critical domain with GoDaddy. Spend a couple of extra dollars and register with a company that respects its customers.

I cannot, at the moment, find a recent article that I read which talked about this very topic and compared terms of various registrars. I do, however, recall that Moniker rated as tops regarding their terms, followed by Enom.
