	They're the same.  I recommend buying the 65xx since
their BU is actually a bit more clued on some of the SP stuff
than the 76xx folks are.  The modular software (while currently
missing ipv6 and mpls stuff) is really the way of the future for
those people who are going to run IOS on their boxes.  The lack of
a modular software from the 76xx BU boggles my mind in many ways.

	It makes a difference which you buy as you're supporting
two different business units, and it's well worth sending the message
to Cisco that the 76xx folks are missing the mark (that is if you agree
with me).

	I recommend using a 65xx with a sup720 w/ pfc3bxl (or 3b if
you don't need to run bgp).  If you're not doing MPLS or IPv6, use
the modular software.  It will likely allow you to patch around that
next PSIRT issue (without reloading) when you can't afford the downtime.
