Get this one. Seriously, the Chinese copies can't hold a candle to it.
Before I knew that there was such a huge fightstick (didn't even know that was a word!)/arcade repair/MAME cabinet community, I bought a Chinese version of this joystick from a popular online DIY electronics company. I was happy with it, for the most part, until I built a custom controller for myself. I ended up looking for shorter buttons (so I could use a thinner enclosure) and thought I would customize the look of my joystick. Well, taking apart the Chinese clone left my fingertips almost bloody raw just to get the restrictor plate off.
So I got this joystick, and the first thing I did was pop the restrictor plate right off and replace the 4-way ring with a circlular ring. All with no problem, with perfectly happy fingers, and all done in 20 seconds without having to pry anything with a flathead screwdriver.
Also, this thing is perfectly even in side-to-side and front-to-back distribution of the "click zones" (the Chinese joystick needed a little bit more distance to the right before a click than to the left), the microswitches have a much higher quality feel to them, and the stick returns to center much more firmly than the Chinese knock-off. This thing just feels like money compared to the Chinese version, even though I probably only paid $5-$7 more for it.Matt
