I touched this in another thread. For my 2600 I've a couple of original Atari joysticks - awful, a speedking (I think it's called) - ok, but uncomfortable and 'clicky', and a Zipstik - chunky, big, a proper joystick. And it suits my Atari.
The PointMaster for the 2600, since the button was in the top middle of the handle (therefore either right- or left-handed people could use it), it was comfortable and sleek-looking (being black), but they weren't real durable though.
I use a Sega Genesis controller when I play. Sometimes the extra two buttons can get in the way since they aren't used but it saves on buying replacement controllers. The Sega Master System controller can also be used. I wouldn't see why you could not use them on a C64 as well.
My problem is I am more used to using a pad controller now then a joystick.

I've just made an offer on a 'Micro-Handler' joystick on UK ebay (Item number: 220891261374). I've not seen anything like it before. You can switch between joystick and paddle control, it would appear.
