not sure if this is quite tactical, but was a similar question asked, so i'll give it a go.
i bought a cheep $15 3rd party gamecube/wii controller. it works fine, but has one small problem, (well, 2 but the other one is most likely me being stupid), the Dstick (direction stick, w/e it's called) sits at neutral, but a slight tap to the right makes it move left, and a light tap to the left is a medium tap left.
as in, it is off center, but when resting does not spam left.
it's perfectly usable for mariokart, was a pain to play LoZ windwaker (aiming hookshot was hard) and i'm not sure if it will be problematic for brawl (i intend to use wii+Nun, so would only be my friends).
the other problem is in melee, the Cstick doesn't work while ingame, but does tilt the menu, which is weird.
the question is, would it be worth my while to find out how to get official controllers, or will that one doo (i'm in AUS)
