Hi Diki

The Abacus is part of the organ range, with the pro model including a 76 note lower manual, stand; swell pedal (With switches) and a pedalboard (Including Toe pistons) plus internal speakers and amplification.

The arranger is the Pegasus Wing and is priced at €2600 Inc. 19% VAT all in, (The Wing also includes the VB3 VST for additional organ sounds) which is the one that is relevant to this forum.

Hope this helps

Bill

BTW: The Abacus Pro is £12,000 so not sure where you got the £8000 from, also since 2010 the single keyboard version is no longer available. (Perhaps the price list you have is from the now defunct Wersi manufacture) best place for prices is www.musicstore.de (The owners of the Wersi brand name)
