The cheapest 2 manuals are arrangers with additional keyboards and pedals added like TRX System https://www.musicland.co.uk/shop/trx-organ-systems-1/ full 2 manual organs start from around £8500 https://www.allensmusiccentre.co.uk/organs/ringway/rs800.html most organs that are purchased are in the £10,000 to 20,000 range, with the main ones being Bohm https://www.keyswerk.de/index.php?a=instrumente and Wersi http://www.wersi.net/ the cheapest 3 manual is probably the Bohm SE60 which costs from around £18,500.

There are also plenty of used models available from various manufactures.

„This old house“ was covered by Shakin‘ Stevens in the 1980s and therefore quite popular in Europe, in the 1950s there was even a German version called „Das alte Haus von Rockie Dockie“, my parents still have the 78 record somewhere in the basement.

Thank you Bill...lots of choice but ...

that SEMPRE SE10/SE20 DB really looks awesome! ..

Bohm is even more expensive then Wersi..

And Wersi has finally nailed support for both vst as well as Yamaha styles up and including the Genos format...

Bohm altough has a mobile version of their organ..

If they would sell a Wersi witouth bass pedals, i would certainly be interested.

I must be missing something! Why the 3ed upper manual?

Flexibility, it is also common in the church, Classic & Theatre organ world where even more manuals are common. (You will also find multiple toe pistons and swell/Expression pedals)
