The DGX505 has great keys(better than CASIO) but I still think the voices pale compares to the CASIO WK3000 series. Right, George Kaye who is a respected dealer that sells and knows all those home keyboards quite well ?

Not only that but the CASIO can download NEW samples of voice. Totally new samples from the websites. You can basically create anything you wanted.

Before you buy it, play the casio for a good 20 minutes and compare the DGX and more than likely you will find the CASIO better by far. Especially the pianos, ep's and almost in every categories.
