The Intel Pro100B can be had for about $45 + s/h and a Cisco 1912 with 8 - 10bT and 1 - 100bT run under $1100 and the 2808 with 8 - 10/100 ports is a bit more than $1600. Not trivial, but their still dropping. It might not be a switch, but the price is trivial for a plain 4 port 10/100 hub from D-Link for $89.
