Ian, that Waldorf piano looks really cool. I can't find anyone selling it in the US.

I recently bought a Kurzweil SP4-7 as a 76 key board for use at home, which I enjoy playing on its own and as a midi controller for rehearsal purposes with my Korg Pa900. I love having the extra keys (but love the light weight of the 61 key board to take out with me).

This would be another cool home studio option. Do you know if you can import any sounds or are you restricted to just what they provide at manufacture?
