I'm starting a special kind of arcade controller (will be revealed via making-of thread) that needs some joysticks. I will be using a hacked 360 controller for the main board, and it will be used to play more than 4-directional games. That being said, I need an affordable source for some analog joysticks. The best I could come up with so far is maybe to find some old PS2 joystick things, or maybe some old PC flight sticks at GoodWill. I just don't know if I may run into any quality issues.
I have a couple more work-around solutions, such as modding the analog sticks from the 360 controller, but I figured I'd ask here in case there was some secret arcade parts suppliers that you all knew about. I would much rather find some actual arcade sticks. All I could find on google were either $150+ sticks and some kind of USB, programmable things. Not to mention a plethora of 4/8-way sticks.
Any help would be nice.
