7301, PA-MC-8E1, 2960S tacked to it for the "switching" side...

Serials on a 6500 require flexwan + PA, and the flexwan is expensive
(and I seem to remember that it's end of support, but that might be the
flexwan1 while the flexwan2 is still supported).  I'd not go there - the
6500 is a great platform for ethernet stuff, but WAN stuff has always been
"bolted to the side", with mixed-quality software support, etc.

With a 7301+2960S, you can get up to 48 switched ports in 2RU, and the
7301 will actually do a better job at BGP+OSPF than the 6500 (because
that's question of CPU, and the 7300 is faster).

A 6500/7600 will need more space, more power, and if all you need is 
10/100, the much higher packet throughput for L3 stuff is likely not
necessary...
