Just want to throw 2 more,cents in. Just came from teaching at the,music store and they have a Privia 700 on the floor. I had a cancelled,lesson so I started,playing around with it . Good keybed and basic Piano for the price,but to be honest the drums left me wanting more. I only played it thru it's,own speakers so I'm sure,it is much better through a good system but I think it may be a disappointment from the G70.
A basic Privia 160 with a,decent Drum Machine may be another way to go.
