Last time I checked small switches where cheaper than (DUAL Speed) HUBs.

Well I usually start with something simpler, like checking the interface
statistics of a switch or computer or just a good old fashioned ping.
There are some problems you can't find with Ethereal (like a duplex
mismatch between a switch and a server) and some problems you can't find
without Ethereal (e.g. A client takes about 20min. to login to a W2K
server because a router *dropping* port 135/tcp.)
It needs some experience to choose the right tool for the job.
