I'd never heard of them, but their deals look promising link here if anyone wants a look. I guess they're a small company which, if they are similar to my ISP Vispa, makes life much simpler when something goes wrong (tend to have UK based helprooms. In my case, I dial a local rate number and get directly through to an engineer). I'll be interested to hear comments on the company.
