Right now, my cluster is on a 10mbps hub. Time to upgrade. (and I ned more
ports).

However, the affordable switches are all unmanaged and offer no port
mirroring capabilities. (aka: ethermon becomes useless when trying to debug
network problems).

One possibility: the Linksys wap/switches (WRT54xx) running linux
(via open-source firmware, eg DD-WRT)

Price is right, ($60-120 USD).

but only 4 switch ports. and No port mirroring, afaik
(afaik, if port mirroring can be done, I'd love to know how)

http://en.wikipedia.org/wiki/WRT54G

But as it says in that article be careful about which version of the hardware
you purchase the later versions of the WRT54G and WRT54GS were first neutered
by reducing flash and Ram memory and then had linux replaced by Vx-Works.
DD-WRT is one of the few third-party firmware to support some of the later
versions (see
http://www.dd-wrt.com/wiki/index.php/Version_5_and_6_Router_Information)
but even it doesn't support the newest hardware version (version 7).
If you are going to buy a WRT54G or WRT54GS you really need to go to the shop
and see the serial number to determine which version it is (and most shops will
probably only have the later versions).

However linksys did release the WRT54GL which is basically the same as the
WRT54G version 4.0 and runs Linux based firmware (and is supported by DD-WRT)
