The newer Yamaha CK88 is $200 off. The price now is $1300. No sale on the 61 key version, at least not at the present time. The 88 has graded hammer action.

I think this is only in the US ( for instance no deal shown at Andertons ), but is from Yamaha so you can get it at many different stores, lots of places like, Sweetwater, Guitar Center, etc, plus direct from Yamaha .
