I found a couple of interesting products:
3com Baseline Switch 2026 (24 10/100 ports + 2 gigabit 150€)
dlink des 1026g (same as above, 126€)
netgear gs116 (16 gigabit ports, 138€)
dlink dgs1016g (same as above, 135€)

So switches with 24 10/100 +2gigabit ports or 16 gigabit ports cost
about the same. Considering that I need 12 ports, what's best for me?
Oh... and I've got a new question: I can't check until tomorrow, but
what if all cables are CAT5 only? Should I discard any gigabit option?

Thanks again!
