Have a look at the sample product list for the Taiwan Piano & Hammer Company.

I like the black keyboard (the specs read as if its a Tyros 3) what is it? Look at the screen size!

So what is that? I found another photo that clearly shows TYROS4 on the outside of the box. EDIT: actually its two seperate photos so it may just be misleading, but here is the inside of the box:

Its a Korg Oasys

I thought they were manufacturers...they are just resellers. Well, it was interesting for 5 minutes...sorry
