Fuck GoDaddy, they always cost twice as much by the time you're ready to enter your CC info. I buy my certificates from a RapidSSL reseller for $12/year. Single root, no chains, recognized everywhere.
Another problem with GoDaddy certs is that they're chained: http://news.ycombinator.com/item?id=1308619 (or at least they used to be), so going with rapidssl or namecheap instead is a better option, and not just b/c of the cost difference.
