Hmm... the Korg Havian 30 does most of what you're asking for. I heard it was being discounted, so maybe they were having trouble moving it. Or maybe they were just clearing it out to make room for a PA700-based model coming soon! And I always thought the TOTL Clavinovas were like a Tyros with hammered action.

I like organ actions (think Hammond SK1) best of all, but there's no reason you can't mate a stage piano to a BK-7m, Ketron SD40, etc. My $.02
