I initially setup a trial account with these guys in May.
After testing there standard web hosting i was so impressed i quickly upgraded to Reseller Hosting.
The hosting is fast and more importantly consistency fast, day or night.
Service wise, they provide RVSite Builder which is a great / simple tool to design a new website.
Best of all support is UK based and very good, they provide clear guidance almost instantly.
Great hosting service with even better support.
