Using InsiderHosting now. Run a couple sites off one account. $10 / month, $1 for a static IP, php and unlimited mysql databases. Works fine, haven't seen it down, they respond quickly to tech tickets, just don't expect anyone to answer the phone. I use Godaddy for all the domain regs, and Dotster for SSL (it's a Thawte certificate @ 1/5 the price, but absolutely clueless support).
