Being one of the authors of NetVisualyzer (a minor one but an author
none the less), I can tell you that it is quite "usable". It has a set
of tools that can show you just which hosts on you network contribute
how much of what kind of traffic. It can show you this in real-time
graphically, or give you summary reports over any time interval that you
want. Its banner tool, netlook, dynamically draws the topology of you
network(s) based on packets it sees and then shows you traffic between
hosts as color-coded lines.
 You can use its extremely powerful filtering capabilities to tell
the tools just what type packets you want to capture and measure based
on things such as protocol, values in protocol headers, sources and
destinations, routed or not, ...Almost anything that you can think of.

Spectrum is a full-blown network management system and developemnt
platform. It is sold and supported by Cabletron Systems. However, we at
SGI work closely with them. Spectrum allows you to look at and control
the actual configuration of all the devices on the network. With it you
can map the physical topology of your network, monitor your companies
organization, assign trouble tickets, keep track of physical location
of your network devices, etc. It gives you the internal configuration
and performance of each of your networking devices. Most of this
information is based on  based on SNMP queries. It is a development
platform in that it allows you to add new applications and device types
to be managed.  NetVisualyzer on the other hand concentrates on network
traffic monitoring, data gathering, and real-time visualization. It is
a closed set of tools. However the two products are lightly, but
effectively integrated.

I believe that the base Spectrum price is approximately $20,000.
NetVisualyzer in its totality is $3995 list.
