Same goes for the Korg Havian, it just fits your budget, its a better piano and a way better Arranger then the DGX-650, it has the same soundsource and style quallity as the Korg Pa range..

But you have to decide yourself, here is a video to make your mind up, personally i prefer the Korg, its way stronger build, got the better sounds (played both of them) and the arranger section is way more advanced. Speaker system is better too (and it looks better)
