Cosel,

In comparing the sounds, ease of use, styles, to other arrangers "if you had the opportunity to of demoed them" 9000 Pro, PA 80, SD1, KN6500, etc... how would you rate the Abacus. Also, how much is the Abacus USD. You said it is worth the price? I was told an unbelievable amount when I called Wersi U.S.A.
