Anyone able to point me to co-location providers located at the Level3 facility in San Francisco?

I've found eFreeServers.com - but their goofy pricing schemes may not work out for my needs. They charge "per server" and the minimum is $200/server... Because I have a firewall and server, I'll end up paying $400 for what I could get elsewhere for $200 to $250.

So I'm hoping I mgiht find another co-location provider that can do more traditional break-out of rack space vs. bandwidth. I'm hoping I can get somone who charges $2.00/GB and $40 per 1U or some other similar setup.

Thanks for any leads.
