staylor,
I like the hammer action of Yamaha P80 better than Roland's RD series. RD's PA-4 hammer action tends to be a little bit sluggish (keys bounce back slower) and requires more finger pressure. I personally like the P80 for its light weight and decent piano sounds. However I find the Yamaha S80 also a wonderful 88-key hammer action keyboard with full synth engine and master keyboard controller (Ymaha P80 does not have much master controller features) and its piano sounds are very nice too. S80 is heavy - above 50 pounds and I only use it at my house. I got one under US$1,400 last Christmas and thought that you might want to know.
