Sorry to hear about the leg, but at least you've got plenty of research time to fill.
You'll not go far wrong with the FC-16 radio, they are expandable via small modules up to gawd knows how many channels, so you can have all sorts of operating features on your boat. I have the F-14 which I use in my Neptune and my Deep Quest, it's comfortable to use (especially when in a tray) it's easy to use and everything feels...right. You know what I mean? Every switch and stick is easy to reach, whether you have big or small hands, there's no stretching of fingers to hit a switch.
I know a lot of the guys on here use Robbe F series radios, and they can't all be wrong, can they?
