The RD700GX looks like a beauty...I especially like the idea of the weighted and hammer action "ivory feel" keyboard.
Yamaha has something similar on it's high end Clavinovas but it only involves the white keys.
The SuperNatural sounds as well as the Tonewheel organs are very interesting...I'm looking forward to trying one.
55 Lbs (not counting a roadcase)seems a lot of weight for the gigging musician.
