No idea about the G 1000 or G 600, but certainly not as the G 800!!!!!

The keys are terrible, but that's because I like weighted/semi weighted keys!

I don't know what chinsy means, but I played a lot of Yamaha's and allthough a lot of unweighted, the keys of the Yamaha have "some feel".

The keys of the VA-7 have no "feel" at all.
(it's handy If you like Hammond glissandro's)

Now, this is my personal opinion only, so just go out and play the damn thing..
