The Cisco 8 port 10/100/1000 switch (WS-C2960G-8TC-L) supports RSPAN which would allow you to tap all the ports even though it's a switch. It's about $750, so it's not a cheap option, but it's not outrageous either. It's the right size also.

True enough. For those of us who need and want something non-switched, eBay and other used hardware places are the only real option.

I don't believe that such a thing ever existed. Hubs that did 10/100, certainly, but I've never ever seen a hub that did gig speeds. When I realized hubs were about to be an endangered species, I started purchasing new and used. I have at least two that (other than testing) have never been used.

The original poster needed to deploy a tap, and a hub (for him) would defeat the purpose entirely. If you really really need a hub (or two), your best bet is to start looking at various resellers. Pity you're not closer; I'm retired, and no longer really need the six or eight that I still have.

In April 1951, Galaxy published C.M. Kornbluth's "The Marching Morons".
The intervening years have proven Kornbluth right.
