Arrangers came late, as I was first playing organs before moving on to a fully computer based system. (I had been using computers since the early 80s which also included music programs)

The downside was that you were locked away in a room rather than in a nice warm lounge, thus when Wersi introduced the OAS series of organs (And sorted the teething problems) I went for a used Abacus (Single manual Organ/arranger) and upgraded it to the latest software which allowed me to use all my computer software on-board in a nice warm lounge. (About 2003)

To this day there is no other arranger/organ that comes even close to allowing the use of professional quality sounds and features on-board, (Still nothing on the hardware arranger/organ front to touch the quality of sounds available in VST instruments) thus I still have it today now running the latest OAS7 software, so it is no different to a new instrument you buy today.
