Hi Donny,
I half considered one again, choice between p121 and a dgx, but , I decided against it, wasn’t really worth paying for the arranger functions, because I was buying the sx900 regardless.
Initially I was planning on having a piano in the living room, and sx900 in my bedroom / studio, but, I managed to sell my 3 korgs , plus the s950 , I had heaps of room left, so piano was going in studio.

I really wouldn’t imagine you’d be happy with one, I think of it more as a piano with styles as an add on, rather than as an arranger.
