We're on BT Broadband (�27) and it seems to do the trick! The difference between them both is that with BT Broadband you get just the connection. With BT Yahoo! Broadband you get extra features like a firewall, email support, spam filter, anti-virus software etc. I would recommend BT Yahoo! to anyone who doesnt know quite so much about the internet security and usage side. Lucky for me im fortunate to know a little about all that stuff so I took the basic option...! Hope that helps.
