I pay for Comcast business class, because (a) I do work from home, and am on call, (b) the SLA says they need to roll a truck within four hours (we've had trouble in our city with line cards going bad and them not being fixed for months), and (c) when I call their tech support, I get someone who is technically competent, or at least wayyyy more effective than the script-reading drones you get on a consumer account.

It's twice the money for half the bandwidth, but I have enough bandwidth and I sleep better at night. Shouldn't be necessary, but . . .
