Keyboard question yamaha & casio?

I would like to know what is the equivalent Casio keyboard of the Yamaha DGX series.So whats the same as the Yamaha DGX series but Casio brand?THanks

Casio Keyboards really aren't that great. They're quite cheap, Yamaha Keyboards are actually better, but it matters what model it is as well, so you can't just say Casio. But usually Yamaha is better.
