Cheap Web & Domain Hosting

[womzilla]

Anyone have a suggestion for a good, inexpensive web and domain host? I suspect I want three or four domains, a half-dozen to a dozen e-mail addresses per domain, and relatively low bandwidth. Third-level domain control (foo.bar.org) would be great, but not absolutely necessary. CGI support (so that I can set up my own installation of Moveable Type) would be nice, too, though I'm actually pretty content with LJ for my online-journaling needs.
