RE: Router with bandwidth management

I don't know much about them, but I see they have a nice GUI.

This solution is quite expensive at more than $2000 a box (at last 
look).  The guy that sells this is very famous for being a difficult person 
-- from what I know, he does the programming and tech support (not a recipe 
for friendly tech support).  And it can't do much more unless you are a 
linux guru -- better to go with the linux or bsd option then.  The Mikrotik 
box is $495 with these features.

Certainly, but it depends on how must power the Cisco box has -- Cisco puts 
the lowest power cpu possible for routing in most boxes and you need to 
check the shaping throughput.
