BazC, Thanks for the interesting translation! I can glean a useful bit from it. The RH3 action is listed on various Korg boards and the SP 250 to the present time, so it would seem reasonable that it is still being made in the Kyota factory. Now with that clearer, the SP 170 "Natural Hammer" action is probably different--I suppose Fatar is a good guess.

Back to the Etudes, and hymn I am working on. Thanks to all.

Yes the NH action is totally different to the RH3, it has a very different feel but my guess would be if Korg are making the RH3 action themselves they're probably making the NH too.

Hey guys,
I went to Guitar Center (again) to try out the keyboards. I think for sure now that I am going to get the p85.
I payed more attention to the Casio's keys and they really have a lot of sideways key movement compared to the Yamaha. Although I like the up and down feed of the Casio keys a little bit better, the uneven spacing which I saw on the Casio is a deal breaker for me.
Also, when I went to Sam Ash (before I went to Guitar center), I noticed someone had bought the p85 display model, which gave me some confidence that this is still a good product.

Unless there is ANOTHER thing that I am not considering, I will be getting a p85 this weekend.
Thanks for the help guys
