Hey,
Reflected can do what you need.
Pricing for the "test server" would run $199/mo for the server and 3mbit included. However, I have no problem giving you a free 30 day trial.
Production dual xeons (2.8's vs. 3.0's) would run $449/mo w/ SCSI including the 10Mbit.
We can quote out the cluster as well, diverse allocations from differing /24's (Class C's) are no problem.
If interested, e-mail phil at reflected dot net. ICQ is 25285313, but I won't be around until tomorrow AM.
I hope you find what you're looking for, even if it's not us
-Phil
