I've had Hostgator for several years and I have been very happy with their service. The tech support has been top notch to say the least. Recently, I ran into a problem installing the new Zend Server and still haven't been able to install it, but the fully explained what the problem was and what had to be done in order to install the server. To make a long story short, you can't install Zend Server if you have CPanel... but I appreciated the fact that they took the time to test the installation on another server running CPanel, and then explaining to me what they found before doing the install on my VPS.
