I'm very happy with A Small Orange (www.aso.com). I found mention of them at www.webhostingtalk.com The latter is a forum on which you may find many web host comparisons. You may also find much high-tech jabber about domain/host-related other stuff if you're into spending some time reading and trading views. Great place!

It depends on what type of hosting you're looking for. http://www.findmyhosting.com is a good place to start. They have a cool search tool.
