Only problem with 7200 these days for primarily ethernet shops (i.e. hosting
/ content providers, metro-e, etc) is like you said... it's not really
powerful enough.  NPE-G2 sounds promising to actually break 1Mpps, but why
spend that much money for Ethernet interfaces-router when you can buy a
usable 6500 package for similar amount of $ with generous discounts :)

Sup32's strongest point is really.. the fact that it has onboard 9x GE (or
2x10GE which isn't linerate but still..) with nicely sized buffers.  MSFC2A
is royal pain though for putting in multiple full feeds (aside from pfc3b
business).
