Inexpensive monitoring tools and bandwidth managers

I'm searching for an inexpensive network monitoring tool for our intranet.
There's a great graphical network monitoring tool for Unix called Scotty, available at wwwhome.cs.utwente.nl/ ~schoenw/scotty/. Scotty contains a Unix Tcl extension for access to network management information and the graphic network editor. Under most Unix systems, Scotty compiles and runs out of the box.
Under Windows NT, the Tcl extension works except for the Internet Control Message Protocol commands. But the graphic network editor is challenged by lack of fileevent support in the NT version of Tcl.
We will soon need intranet services. Our problem is availability of WAN bandwidth and relegation to 10M bit/sec Ethernet on the LAN edges. I saw a presentation on Packeteer's PacketShaper, which provides quality-of-service enhancements by letting network analysts and designers filter TCP applications and guarantee or limit the amount of bandwidth an application can occupy. Is it an emerging technology or an expensive way to save money?
I've received favorable reports from colleagues testing and using PacketShaper. Reviews from Network World (see the review) and others also are positive.
