Find Rockhoster.com to be incredibly Perfect. Work of transferring all my websites to this web hosting provider.
Excellent and fast service, excellent stuff for open source project like Joomla, Mambo, etc. and good prices and tutorial for all level´s knowledgeable people.

I do not know of another webhost that offers that level of customer support and satisfaction. Recommend them for those who want to run commercial websites.
It's a nice web host because they offer a wide range of plans for each kind of users. This web host is well priced and within everyone's budget. So far they have been excellent.
