As of this writing, Newegg has in stock both Xbox 360 and PlayStation 3 flavors of the Madcatz Tournament Edition Fight Sticks, the badass joysticks specially made for Street Fighter IV that have been in extremely short supply since the game's February release.
Jeff Gerstmann of Giantbomb.com said, "It's probably the best console joystick I've ever used, and the only one I would use to play Street Fighter IV... or Raiden Fighters Aces." You hear that? Probably. A ringing endorsement!
The sticks ain't exactly cheap at a list price of $149.99--and even at that premium price, they're sure to move fast. So if you want one, do act quickly.
UPDATE: The 360 sticks are already gone, though the PS3 ones are still holding steady for the moment.
UPDATE 2 TO CRUSH THE REMAINDER OF YOUR DREAMS: The PS3 sticks are now also sold out.
