Thanks Ricky,
I've ordered a VPS from Webfusion, and while its only been a month I would recommend them to anyone that's looking for a host in the UK. I was put off by some of the bad reviews I'd seen but all seems good so far, and worth the risk. My few dealings with support have been positive. I suppose the real test of a host is when its not all plain sailing and something goes wrong, which I've not experienced yet but so far so good.
