Gree about the price, the Sup720 seems like clearly better value for
the money.

Misunderstanding. This applies to the Sup2/PFC2, which has 256K hardware
entries in the TCAM and gets halved if you turn on uRPF. The Sup720 also
has 256K entries, but does *not* experience the "halving" when turning
on uRPF. (This is documented on Cisco's web site, but you need to look
for it...)
