Yes I think your mind is made up now your doomed

its a great Bike
Best for your money should be here (the reason is many have bitts on that dealers may remove and your going to want bitts, also you would generaly have threads here about the bike

all cherished

) you will see cheaper ones but minus the bitts
I think with most F800gs's Im right in saying the main thing they have that the f650 does not have is the "switch" you can just flick it on when ever you like you may be passing a shop window (like Debenhams) and you can give it a flick, maybe when you passing a F650GStwin (unless we loose you on the twisties of course) some leave it on all the time.
But whatever you do use it and have Fun
good luck with your purchase

and ride safe
