Hi Allan

You will need to try a few out as the operation and sound is very personal, however for gig ready Hammond or Nord with a Ketron SD40 would be a good place to start. If you are prepared to spend more than have a look at the Wersi OAX1 Duo, which is easily dismantled for transport and used in whatever configuration suits the gig. (Also if you can still find one and don’t mind setting everything up beforehand have a look at the Roland Atelier 300 (Not the best to play on the fly though) for a nice little package)

Have fun

Bill
