Whats the best host for PHP - Facebook App?

Hi, We are using PHP with Yii Framework. Currently we are using MySQL but will also use a NoSQL database in the next application. For Facebook app, we need an SSL too. We have no experience in UNIX and System administration - dont want to take on much management work either. Can you suggest a good hosting service at cheap to test our app prototypes? Thanks.

Thanks Gee. We are currently on Linode. But now Im experimenting with PHPFog. Looks good so far.
