Rating : - LOVE <3 IT but there are things you should know
The quality is 5 stars and this unit will not disapoint you.

But here is what might.
As you may have already read this does come with a power supply. When I baught mine i got it without it and the unit only cost me about $170. While this bundle is nice i think they are charging you almost 30 bucks for the power supply.

ALso finding out from yamaha what powersupply they recomend is like pulling teeth (by hand).

There is a locking bolt on the bottum of this to attach it securly to a stand. NONE of the stands under $100 use this bolt they just sit the keyboard on rubber stubs.

STILL I 10000% recomend this unit and all in all what it has taken me to get a power supply i think the price hike here might be worth it.
