hehe a DS-3 to my house - now THAT would be geek nirvana.

that?"

Maybe that's what is $30K a month.... I'm not sure. Maybe the OC-3 is
$60K a month. I wish I could find some example pricing somewhere online.
It would be nice to know. I guess I could find out how much they really
are, but then I don't think I could tell any one. :-)

If OC-3 is only 30k a month, how much is DS-3?
