Need hardware firewall with traffic management and reports?

any recommendations please?

need to buy lots of these to handle bonded T1 and fiber setups....

It needs to be a hardware device (preferably rack mounted), and it needs to be able to do the following:

1) show heaviest users by IP, and what ports they are using, how much data (basically live reports)

2) must be able to traffic shape, prioritize types of traffic etc etc

3) be installed in a "passive" setup, or be installed to do Nat, one to one Nat, etc etc

I have searcehd google endlessly and not having much luck.....

any ideas or hints for me please? thanks
