Hi Mike: Panasonic-Technics produces a great line of 'fully weighted action' arranger style keyboards

in their "Digital Ensemble" Line:

I have performed on the Sx PR-703 and it has the SAME 'auto accompaniment type' features as the KN (KN6500/6000) keyboard line, but with fully weighted keys. The piano sound and action is terrific IMHO. If you need 88 fully weighted keys then the PR-703 or PR903 may definitely be the one for you. You will need to go to a traditinal piano/organ store that carries the Technics line to see them. - Scott
