de WB2CPN They're not all that much different. It depends on how you use them. I got a 706 when I thought I would be out-of-service for a while, then changed up to a MKIIG. Well, I stayed in service, (not even a wheelchair), and now I keep the G on MARS. It gets more use than the 756II here does. My ham radio friend has the 706, and he is happy with it. 73 Clete
