Latest, same money, newer hardware, so 7604 RSP720-3CXL.

You need OC3 ports? Yeah, you're going to be paying a lot for SIP-400+SPA, 
it'll do 4 gigabit/s actual traffic.

Yes.

Full BGP table costs money, if you're on a budget, get a used Cisco 12000, 
it'll take you into the gigabits/s realm quite cheaply, then when you're 
past that, go for 7600.

7600 makes a lot of sense if you're ethernet only, the SONET/SDH 
interfaces are quite pricey due to the need for SIP/SPAs.
