thats true, but they are just so incredible expensive...
If you compare them with the completion (Bohm, Bemore, Lowrey (And the Roland Atelier before they were discontinued) they are not expensive, apart from Ringway they are the cheapest full entertainment organ in Europe and US Markets. NOTE: Don’t compare them with arrangers, as they are 2 totally separate instruments, even though are certain similarities. (The backing on an organ needs to be simple so as not to get in the way of playing, whereas an arranger needs full blown backing as they are more limited when it comes actually playing)
The only arranger that Wersi make is the Pegasus Wing, and this is no more expensive than other arrangers.
Comparing an organ to an arranger is like comparing a Workstation to an arranger, they have similarities, but playing them is totally different.
