A lot of users who used to use arrangers have either gone back to organs, (You can pick up a decent used one for next door to nothing) or added a 2nd keyboard to increase flexibility.
While arranger bass is good, it still becomes boring and monotonous as it doesn’t have any feel, unlike if you play the pedals yourself.
You can import one the latest Yamaha organs via Taro Trade in Japan if you want to go back to a Yamaha organ.
