I prefer light, responsive action, certainly not weighted. However, I also prefer 76 keys.
Both the Roland G70 and Ketron SD1 and Audya work great, although my semi-arthritic right wrist knows by the end of the four-hour night that there is a little more resistance.
Only true, weighted piano action would be a deal-killer at this time, but in a few more years I may be forced to use the lightest action available, even at the expense of 76 notes.
