I use MediaTemple, and what I like is that it's a company geared towards a category of developers, and not ANY person who wants a website. So the services and support are commensurate for a company that offers services primarily aimed at professional design-oriented firms and/or developers, and not Joe Schmo "Website Author." Service request responses have always been quick, I've never lost data, had a website disappear altogether, etc...
The GRID server configuration is nice at a $20 pricepoint. With PHP5 supported and safe_mode turned off, I can't wait to get off the shared server. Shawn Inman is a modestly-famous web designer/developer who uses MediaTemple for his website: http://www.shauninman.com/ -- Jared Farrish Intermediate Web Developer Denton, Tx Abraham Maslow: "If the only tool you have is a hammer, you tend to see every problem as a nail." $$
