Wayne,
I sell both brands and I agree with you that the Casio sounds better than the Yamaha. I would suggest the WK3000 or WK3500 over the DGX202 both for sound, features and value. Keyboard Magazine also agrees with both of us in their review of this keyboard this month. They say you can't find another keyboard under $1000.00 to compare. Please contact me if you need any more information.
