My N64 is about as sturdy, except for its second controller (I think; haven't played in forever, but remember it being shit, which I think happened after my older brother got pissed at KI: Gold), and my only issue with my Gamecube one is sometimes up on the control stick won't do anything, I think cause sometimes I leave it at rest, not realizing the control stick is pointed up for long periods of time, but it's been working just fine lately.
Nintendo equipment in general is like the damn Energizer bunny though, it all just keeps going, even if you adopt at launch it seems. lol
