We don't serve a market. We are a private business. We are multi-homed with multiple providers, none of which is an eyeball network. Even if we wanted to peer, most of them are not available in our area, but our the only choice for some of our employees.

Cogent still has congestion issues at various peering points as has been reported in this and other mailing lists recently. Like I said, if VOIP and VPN aren't an issue, go ahead and use cogent. But if packet loss makes your access useless, then avoid them if it all possible. YMMV.
