Don't throw out your old hubs. It's hard to find a 10/100 hub for sale
any more. Even the cheap consumer devices are switches. I picked up a
$25 hub at Fry's a few weeks ago just in case I ever wanted to casually
snoop some traffic. But Fry's is sold out.
The netoptics.com link posted was "priceless". I'm always wary of
simple products that are expensive enough to have a request for quote,
rather than a price, on their web page.
