I think the best place for your own web sites is VPS
I can recommend you the companies like
Rated #1 Fastest PHP 5 Web Hosting in U.S.A, Magento Hosting, SSD Hosting, Zend Framework Hosting, Joomla Hosting, Wordpress Hosting (VPS)
and
HostingSource Inc. - Web Hosting Solutions
Just do not waste your time for the extra cheap services
remember you get what you pay for
Good luck
