It really depends on many factors. For instance, how much £££ do you want to spend?... will you be using the radio for models other than boats?... how many channels do you need?... etc, etc.
It gets even more daunting when you have to decide whether you want to go the 2.4GHz route, or if you want to stay with good old 35/40MHz.
The latest kids on the block are those snazzy offerings from Spektrum. Just about every owner of the DX6 and DX7 radios will tell that they are the best things since sliced bread - and deservedly so. Likewise, every owner of Futaba radios will tell you the same.
Ultimately, the final choice is down to you. But whichever radio you decide to go for, you can rest assured that you will be happy with your choice.
By the way, computerised radios are not to be be feared. You say you don't want anything complicated. Fret not, for if you can operate your PC, then it's a foregone conclusion that you'll have mastered the radio programming in not time at all.
My suggestion would be to buy one that YOU like.
Just go for it and enjoy the thing.
