I would love to have one sitting in my living room, I have the CVP307 now. What I would like and what makes sense is another story. I use the CVP307 for working on piano stuff believe it or not I also use the Pa4x-76 for piano stuff because of it's excellent action.
Anyway I'm going to guess it will be close to $10,000 here in the states, that is unless you have a connection to a Yamaha dealer who you used to work for and would sell it to you at cost plus shipping.
With that said I wouldn't buy the CVP809 because my current CVP is used for piano only it would be overkill for me for home and since transporting it to a gig just won't happen. As much as I love the CVP the dollars would be better invested in an acoustic grand piano because the value of those don't drop and have a tendency to appreciate in value. I laid at $4500 for the CVP somewhere around 2005 and that was at dealer cost from the Yamaha dealer I had worked for in the 70s. I'd be lucky to get $2000 for it today On the flip side of things I sold my Samick Grand some years ago, I owned it for about 8 years and I sold it for the original price I paid for it.
Below is the photo of the CVP 307 that was on line.
