Rick,
Yamaha announced back in January a replacement for the current DGX505 model which will be coming out in June. There will be a hammer weighted model and a semi weighted (like the current DGX505). The Hammer Weighted model will sell for about $895.00 if my memory serves me. The features will all remain but the cosmetics will change a bit. The current casio model is now called the PX555R which sells for $795.00 and like the Yamaha includes the stand.
