Analog Joystick

I have a project and I need an analog joystick.


The only model I found searching on the net is the "Advanced Gravis Joystick",

but it's kind of old and I was wondering if there are similar ones out there.

In the worst case, a digital joystick would be OK too, but it should have 16 directions or more.

I could only find a 8 directions ones, like Speedlink's SL-6603 Competition Pro stick.


Any suggestions are appreciated.

Thanks.
