I use
34sp it costs £17.95 per year, but if you carry their advert in your home page, they'll credit you with a penny-a-day, saving you £3.65/6.
It's not great if you have a shed-load of content, and expect lots of hits and downloads, But for a basic web presence, I have no complaints.
Also a .co.uk domain costs around a tenner for 2 years.
I can't remember any downtime in the 7 years I've been using them.
