Really enjoy this site. A lot of very good information for anyone trying to figure out what arranger keyboard to purchase. Now, if I lived near George Kaye's store I probably would not have to ask this question. I tried out a PSR 9000 for 5 minutes today and the one thing I noticed was the synth type action. Now, I'm not expecting a Yamaha P200 weighted action in an arranger keyboard (I guess that would be a little to much to ask?) but if I were considering a Solton SD1,Technics KN6500 or a Yamaha 9000 pro,which unit's keyboard would be the most weighted, which of the three would be the least (more synth-like) weighted? Thanks!
