I've had enough of crap speeds & crap e-mail through ntl:, and the phone call I had this morning blaming it on my firewall settings was enough to tip me over the edge

I don't want this to be a "PM me your details and we'll look into it" thread because quite frankly, I've had enough of it (no offence to anyone that helps on this site, I'm just fed-up of being pushed around different departments at ntl)
Oh, and the e-mail issue? That's only occurred recently & is a temporary hardware problem
So, I know not everyone on this site is an ntl broadband customer : what are your recommendations for ADSL suppliers? I've looked at a couple of review sites but there's so many there
Oh, and what are the networking restrictions for ADSL? I have 3 PC's here that all need access to the 'net, all going through a router atm
Thanks in advance for any help!
