Yes, Bob, I see those old D700 at hamfests regularly. Add to the list of full-duplex HTs the Yaesu FT-51R. I bought mine on ebay years ago for way less than it costs to go to a Texans game. I did a quick check and found one for sale: http://www.ebay.com/itm/YAESU-FT-51R-2M-440MHZ-PAGING-TRANCEIVER-PORTABLE-4-...
An old HT almost always needs a new aftermarket battery (or two) if you plan on actually using it handheld. 73, Jerry, K5OE
You omitted all of the other full duplex radios: The D7 and D72 HT's and D700 and D710 mobiles.
Full-duplex has a very important purpose in the satellite world. you don't need base-station radios like the Icom IC-9100, IC-910, Kenwood TS-2000, or Yaesu FT-847. If you own two handhelds, chances are you have what you need!
There are 10's of thousands of these Kenwood radios out there, and many people upgraded from the D7 and D700 to the D72 and D710 for the enhanced APRS functions. But the full duplex dual band radios remain the best there is for full duplex FM satellite AND APRS satellite work.
