to add my bit...i have the e-50 (on top of my yammie s90es)and it does sound quite good throught the PA.... but now i am seriously considering (even to the point of getting my dealer to get a "price" for me) moving up to the g70, and ditching the e-50 and the yamaha...i might consider a motif es rack, but that is ONLY for the electric guitar sounds, nothing else...and if roland add the OS updates diki has mentioned, as i think they are essential, especially the chord sequencer, then choosing the g70 is a no-brainer...(when was the last time you got an os update from yamaha??)
