I have had the best luck, and most experience with, Kenwood dual-banders 
on satellites. I've been using the TM-D700 and TM-D710 series on all the 
available FM satellites for the past six years with great success.  With 
TM-D700's being available at bargain prices sometimes, it is hard to 
spend triple for a new TM-D710 (although they're quite nice.)

Almost any manufacturer's rig I have tried do not support cross-band/VFO 
"split" memory channels for full duplex. It's no problem because you can 
open a separate memory on one VFO for uplink and another memory channel 
on the other VFO for downlink.
