David,

The GA-3 was and still is considered one of the best organs Technics produced. I have a friend and ex manager of a Technics Store that has owned a GA-3 and purchased another for her husband to play duo and as a backup.

If I had the room I would be looking for a GA-3 myself. Not sure what they will cost in the UK, but they are in the range of $2000 and $3000, if you can find one.
