Yeah, I've noticed the spotty control sticks on third-party controllers too. I've got a third-party GC controller (Spider-man, now that I think of it; the only reason I got it was cuz it was in a $20 2-pack, yet one of them was already broken ) and it's overly sensitive. I have trouble playing the Zelda Collector's Edition disc because it's hard as hell to aim the bow/slingshot.
