BH,
You opened up a can of worms for all of us to climb out of the walls, all with subjective opinons as to what we like. In arranger keyboards I've had a PSR 9000 and now have a PA 80.
I think both are excellent arranger boards, but I will key in on one thing you said and that is the organs....I think the PA has better organs digital drawbars etc. I think the 9000 has better pianos, the rest is probably a closer coin flip.
I think the PA 80 operates a bit easier for me than my 9000 did. The PA has tons of downloadable styles, today I think Fabio put 200+ styles up for download free from all different genres. I think the final decision will come down to you sitting and playing both for sound and user friendliness, because you'll like some things better on one then something better on the other etc.
Not knowing a whole lot about you off the top of my head, I would think the VA 7 might be more than you're looking for a bit more difficult to get around, a bit more expensive than the PA anyway and I think you'll find it has more features on it then I think you need or want.
As far as having a salesperson that is knowledgable.....in my experience don't count on it, do your homework and just call on them for two things. 1. Could you plug this in please 2. How much.
