Used them for a couple years so far.
You can set up for as little at £10GBP,, have them 'look after' your domain name, but point it at another providers DNS, was rec'd to me from a newsgroup I follow, and I've never had a complaint.
They also do a £10GBP hosting package too.
It's basic to start with, but they'll upgrade you whenever, you get proper POP3 email accounts.
I have 3 domains with them right now, and all 3 are hosted elsewhere.
