How about one of these
While that is fantastic to play on it is a bit big so for day to day Amiga gaming I still go to the joypad and usually the CD32 pad.
I just find a single joystick difficult to hold while wrestling the stick in whatever direction and trying to smash buttons. Maybe I'm just to used to joypads. There is also the thing of old joysticks feeling very flimsy, I have a few on which the plastic groans as you move it about. A zip stick though has a nice solid feel.
