Sam's Club does sell it for $699 with a bench. I bet we could get at least as good of a price out of George Kaye or Dano without supporting Walmart.

Sam's Club sells a PX400. I don't know how this differs from the PX400R.

I would never buy this piece for it's accompaniment function. For me, that feature is just a toy.

I have never tried the WKs, but I would be positive that the piano sample on the PX400R is better.

When I played it at Guitar Center, I had some relative quiet, and I was impressed with the piano sample. Definitely better than my PSR3000's piano sample.
