Fred Karpoff's "3-D Piano"

[cysorz]

Has anybody tried Fred Karpoff's '3-D Piano'?
Any review of the content? Is it worth ~$300?

I am currently working with Seymour Fink's DVD, but I need more 'visual' material. Any recommendations?

I worked w/Seymour Fink's DVD and book many years ago and got a lot of good ideas. When I saw he endorsed Karpoff's 3-D Piano I ordered it. All I can say is WOW!! The instruction and visuals are stunning. I've been working w/it for over 4 mos so far and still am learning more. I can truly say that my playings never been better. I saw more footage at claviercompanion's site before I bought. My friend bought last month and said they offered a guarantee, but that wasn't offered before (and I don't see that on the site now). No matter, I'd never return it!!
