  The WS-C1400 is a *wonderful* concentrator.  We bought a few of them
at Digex back in '95 or so, paid close to $20K/ea for them.  Now
they're $100-200 on eBay.  I've emailed the $899 guy, explaining the
facts of resale life to him.

  Just keep searching on eBay...they'll turn up.

  I agree...this is a very bad idea...

  Yes...I use Cisco WS-C1200 Workgroup Stack ethernet switches with
DAS FDDI uplinks.  They sometimes go as cheap as $50 on eBay, and they
work VERY well...they even do VLANs.  The ethernet ports are only
10baseT, but all of the serious computers here have FDDI interfaces.
