I compared over 25 shared hosting providers with servers located in US. Finally 7 months ago I decided to give Gigapros team a try. They offered me a good shared hosting account that suited my needs. I run Joomla web site with them and must say that everything works like a clock.
The service and support is amazing. I have asked numerous questions and they have never responded in less than 15 minutes (most of the time they respond within 3-5 minutes). Pretty amazing. I have subsequently have encouraged at least 3 other people to sign up (and none have had problems).
I recommend Gigapros to other people looking for professional hosting service.
