Okay, I'm going to withdraw my suggestion for the SFA stick. Now that I drag it out of the closet and play it again, it's quite possibly the most uncomfortable joystick I've ever used (Next to the PS2 shadowblade) and even if you mod it, the height of the casing makes it awkward to play on. (I play all my games sitting in a chair with the stick on a table) Also, one of the boards is defective.
The next thing I was going to recommend is the Pelican Real Arcade Universal, it also has the Chinese parts, but it's a pretty decent joystick as far as retail console sticks go. I still have one, I bought it an a Gamestop the day I bought my Xbox. But unfortunately it didn't work with the PS2 adapter.
I think that leaves you with the Real Arcade. I'd keep in mind that the Shoryuken review was written by fighting game elitists, and less than the best generally doesn't cut it over there. The X-arcade seems to be just fine for everyone else,
here's the Digital Press review by Don Evanoff. You don't have to worry about adapters or modding or anything, and if you want a Neo Geo layout without that second button down there, you can always pull it out and stick in one of
these bad boys.
So, I think the X-Arcade would be the best choice for you after all.
