Their scalable infrastructure is fast and you can easily upgrade if you need to. Used them for years, the CEO even responds to support tickets personally from time to time. I'm a web developer so I know what you need for a website to not get strawberry floated up by the hosting service, which has literally never happened.
I only pay £15 a year which is ridiculous, but I've used much more expensive packages from them.
They will also migrate from your existing hosting for free which probably makes your money back 10 fold as a business.
Never listen to anything anyone says on a telephone, but if you need to call these guys they do pick up and know what they're talking about.
