Agreed.  
This 9-port setup is the most cost-effective Cisco solution, I think.

6500/7600 show that they are switches when you have overlapping VLAN IDs and
want to (L3) trunk on several ports.  It is not possible to have a L3 port
with 802.1q subinterfaces, and using SVIs is out because of overlapping
VLANs.
For nearly all other purposes, the platform is a high-performance router...

As far as I can see, the 7300 doesn't have native FE-port adapters, meaning
that we would need one carrier card for every PA-2FE-TX.
As someone else remarked: "Prepare yourself to pay dearly." :-)
