Looking for a good protocol analyzer or network sniffer

["Giddens, Robert" <GiddensRobert () bfusa com>]

I am currently in the market for a good network analysis tool or
protocol analyzer for the network that I manage.  I currently use
Ethereal but want something more GUI based with better capabilities.
 
I have a Cisco switched network.  One 4500 Core Switch with Fiber Gig to
all the area switches.  In the 4500 I have Sup IV cards and plan to use
layer 3 (via EIGRP) directly on the switch.  Most device connections are
Copper running 100 Meg.  I have seen some very crazy pricing on the Gig
stuff so I think my budget will keep me in the 100 Meg area.  I do have
access to a corporate office that could provide the Gig support.
 
I have looked at EtherPeek NX (WildPackets) and the Network Instruments
stuff.  I currently use the ProConvert from WildPackets to convert the
traces I get from one product to another.
 
Thanks for your input!!!!
