I have the KeyB Duo MK111 which is the ergonomically almost an exact copy of a B3. It's essentially the same as the Viscount Legend. I couldn't find enough differences to make me want to upgrade so I suspect this will be my last organ. I've been living with the PK7a bass pedals but will probably replace them at some point with the 25 pedal Legend set.

The Seven is great but the 'acoustic' piano isn't good enough to stop me from lusting for something of the quality of your FP90 . I have an acoustic grand up in the living room but when I downsize (which I must...soon), I'll be looking for a nice stage piano to complete the 'big three' (B3, Rhodes, AP).
