Lightweight stage piano with full hammer action?

[danlondon]

I'm looking gor a stage piano that I can take around London on the tube, but with a feel as close to a piano as possible. My current one is 19.5kg and that's too much (hoping for under 15kg), but I would really like hammer action as I'm doing solo gigs where the piano work is important. Does anyone have any suggestions please?

I would also be happy to consider a controller and connecting unit if that kept the weight lower for the same quality.

Thanks in advance
