Godaddy is pretty decent for shared hosting. I've been using them for a while.....decent pricing, and service. But if you're looking for dedicated, you can prolly find some other better place.

Im sure other people here might be able to tell you more about dedicated hosting, but I think in my experience,  most of the time for huge sites and larger bandwidth, its cheaper to buy a box and pay someone to get it connected to a bigger uplink line if you know how to do server admin stuff.
