BH,
Where do you live? Are you close to Southern California? Come see me! I'll show you and demonstrate every keyboard you have mentioned except for the Technics because I don't sell technics. Jocko mentions the PA80 and the PSR9000 being less expensive than the VA7, but now the VA7 is the same price at my store as the PA80 ($1995.00). You need to check out all of these. Under $2000.00 check out the VA7, VA5 and PA80. Over will be the technics and Yamaha. The Solton is also in this price range. You can't go wrong with any of these products.
