I have been successful with the VX6, no need for Doppler or full deuplex,
just program in the channels for every 5 khz on the receive, in the range of
+/- 1- kHz, and tune manually during the pass.  Manual solution, works well
without the need for detailed Doppler.  Besides, on the FM repeater birds
there is some FM "capture effect" which is to your advantage...no need to be
spot on for the receive freq

 I think the new Yaesu VX8r is full duplex. I recently purchased one, but 
haven't had a chance to get on the FM voice sats with it yet, to see how 
well it works. It  does run APRS well with it's add-on GPS, I did get it to 
digi via ISS. I can't wait for it  to get warm, so I can do some more stuff
