I've been fairly happy with Comcast for the past couple of years. It is somewhat pricy, but my work pays for part (so they can call and have me fix things in the middle of the night) I don't use the software that came packaged with the service, since the normal browsers and e-mail clients work fine without it with less overhead. I do have a router to act as a NAT firewall to protect the little LAN (only 5 machines), and it has worked well at preventing attacks so far.
I haven't had much experience with their customer support, since I haven't really needed it. They did just increase the size of mailboxes and web regions significantly - I think to 2 GB on the web/file storage areas.
Just my $0.02
