I must be alone in that I've never had a bad customer service experience with Comcast. They've always been able to resolve problems, and service outages in my area are extremely rare. My only beef is with the price I'm paying (around $130 for 50MBps + basic TV), but their Internet service so far has been stellar. They were also one of the first major US ISPs to take IPV6 seriously and roll out native support.
