I'm using phpwebhosting too.
My only beef is that their control panel isn't as great as it could be. There are a lot of things (like making subdomains, databases, etc) that you have to send them a support request for. These take time, and I know they could be automated if someone wanted to sit down and write a script for it (the guys at www.l33t.ca (they're free, and they're down almost constantly) did it).
Overall, I'm pretty happy with PHPWH... they're fast, reliable, and they dont charge for anything over the $10/mo. I'd recommend them.
