Here’s something for you to puzzle over:

The Wersi Abacus has 61 notes, onboard speakers, 8.4” touch screen, Drawbars, Floppy, DVD/CD Burner and USB 2, it is also very heavy (Transportable rather then portable)

The Wersi Ikarus has 76 notes, onboard speakers, 8.4” adjustable touch screen, Sliders, Floppy, DVD/CD Burner and USB 2, however it weighs only a fraction more then a Roland G 70, is no bigger then an Abacus (The height is actually less) and costs a 1/3 less.

Sort of blows the theory that a 76 note board is more expensive to make and has a weight penalty.

BTW The Abacus comes from the Organ line, whereas the Ikarus comes from the Keyboard line. (In case you were wondering)
