I've used these, I've got 3 sites sites been running for 2 months now. At first I just bought the lowest set-up because - well I hadn't heard of them before - Within the 1st month I was impressed to upgrade.
These are just one of the 3 hosts I use and for the price, so far, it's been well worth it. I'm not yet prepared to host my very importent sites here but I'm not far from it. At the moment they are not VAT registered so thats a saving and I wouldn't put any Wordpress blogger off choosing these guys. Here's one of my http://footballinprint.com test it out.
