I like 90megs.com
I have a free account with 90megs.com. They provide an ad-free 90mb plan, with a 10gb/month bandwidth. The plan features Cpanel (which is said to be the best commercial control panel) and Fantastico, which with one click installs any one of numerous PHP scripts (website templates, forms, weblogs and publishers, portals, photo galleries, etc.). The free accounts enable Perl and CGI programming and scripts, too.
I've been with them for about a month now and their servers are relatively fast. There's been almost zero down time and they don't pester their users.
I have two sites with them research.90megs.com and
