I'm curious as to the problem wih Cable- or is it just that you cannot get it in the area?
Bingo.Zen were good - the only problem I ever had with them, was the price. £24.99 just for broadband. I also had 1GB of webspace but it didn't support PHP/MySQL or anything.
Wouldn't mind Orange Broadband but I've heard a lot of stories about problems with mail servers etc.
