Really?  Did you mean to say switch?  I normally think a single NIC will
cost that much.

Ahh.  I guess you did mean "NIC" in the first paragraph.  Good.  I mean ...
Dang it.  It would have been nice if you found switches for $500...

Actually, a switch with 2x 10G uplinks is better than a crossover because at
least you have the option of using other systems on the same switch at 1G.  

I know they're out there...  For whatever reason, 10G seems to require 10G
module bays instead of simply an SFP module.  So after buying a switch, you
need the module bay adapter, plus the SFP.  It's real expensive.  But here's
one example of a switch that has 4x 10G slots:
