This is an excellent host; we use them...
For about 80 quid we have for two years got:
Unlimited bandwidth
Unlimited web space
Unlimited POP3/forwarding e-mail accounts
PHP4
MySQL (1 database)
Perl
A .co.uk domain
A good web-based control panel
VERY fast tech support
And some other crap I've probably forgotten...
They do do cheaper deals as well.
When I say fast tech support, I mean fast!
I've had to e-mail them twice. First time I got a reply after two minutes, the second time after three.
From what I've used, a very good host!
