Man, atari2600.com has a controller for $52 - that's almost as much as I spent for the Vectrex, controller and two games (one in box)!
That's because they're very valuable and desireable, as much as the console itself. The custom arcade style self centering control stick is impossible to replace if it breaks down (your only option being to convert Genesis or other controllers for an entire replacement of the controller). That's also why this is important - do not lay in to the stick with your thumb like a PS analog stick. They're designed to be held between the fingers (usually thumb and forefinger). I can't tell you how many kids I've had to kick off the one I have on display at the MGC because they refuse to play it without thumbing the top and pressing down.
As far as your problem, it's a common one. Underneath the buttons is a button contact strip - a literal sheet of rubber that runs the length of the buttons and has raised domes on it - these crack and split over time. You can open it up and restabalize the tops of the domes with rubber glue, a hardening epoxy, or similar.
As far as opening it up, the screws are underneath the controller overlay. Some people have managed to slowly pry it up with a small knife, but the common (and less invasive way) would be to heat up the overlay (and therefore the industrial glue underneath) with a hot air gun. As the glue desolidifies, work up overlay evenly from all sides with something thin, long, and flat. If you try and peel it from one side to the other or peel up any of the corners, the overlay will loose it's flatness (it's not a flimsy decal) since you're curving the surface. Once you lift it up, simply remove the screws and pry the case apart and you'll see the strip. Take it off and apply the glue to both sides of the dome top, with which you're simply "remolding" the dome top. When you put it back together, to put the overlay back you can simply reheat the entire overlay and any industrial glue left over on the case top, or get a hot glue gun.
