Seconding this.

They're not the cheapest in the market, but their market positioning is pro-privacy, anti-censorship, high customer service for expert users.

My connection with them has proved very reliable. I haven't had much cause to use their support, but when I have they've been helpful and communicative.

For plain ADSL they look to be about 40% more than others IIRC, £35 vs £25 (and they have setup fees).

In the past when I've looked they've appeared to be amongst the most expensive.
