After watching eBay for a few weeks, I have a good picture of the cost of used multi-mode equipment.  I have included items below that were sold on eBay, their "item number" and their cost.  You can copy the item number and search for them on www.ebay.com to get further information on the equipment.  Please note, these items have already sold and are included here so we can get an idea of the cost of things on eBay.  You can also search the web for the model numbers to learn more about the equipment.

 

All of this equipment has at least 2-meter SSB capabilities (and sometimes more bands) and it reported to be in good operating condition:
