So I compared the keyboard sounds of this WK-200 vs. the $200 Yamaha that's at Sam's Club, the DGX230MS....

The Casio runs circles around the Yamaha; when I expected it would be the other way around. Seriously, the Yamaha has about 5 EP sounds in it - the first one is a CP80 sample. The rest are flavors of DX sounding EP's, which had their day but haven't really stood the test of time. Never liked the sound of the CP80, but I did like the DX EP sounds back in the day, but no longer. The Casio has bonafide Wurly and Rhodes knockoff sounds in spades. I would totally gig with that as an EP, at under $150!
