I would recommend a Cisco 2950 series switch.  You can
set up a span port that mirrors one or multiple ports
both directions.  Most cheap managed switches only
mirror one direction.  

The 2950 series switches cost about the same as most
managed switches and have good performace and you are
still in the "REAL SWITCH" world.  Cisco has a
lifetime warranty and will replace them without a
support contract if they fail.

We use the 2950T switch (2 copper Gig ports) for our
snort sensors.

more than 100Mbps)

I have only worked with "real" switches like Cisco
Catalyst 3500, so I
have no frame of reference as to where to begin
looking. I don't want to
buy cheap crappy stuff that overheat and die after a

What switch brand and model should I take a look at?
