DLink's got an 8-port (unmanaged) 10/100 mbps switch that'll do the job; it's already under us$100 here in Southern California. It's not in a Rack-mount format, but I think (not sure, though) it fits into 1U of space.
What I've heard about cheap hubs is that they have a tendency to overheat and stop working when used 24/7.
At that price/performance ratio, the switch rather than a hub is a no-brainer.
I agree. Howard Sacks webmaster@xxxxxxxxxxxx
