sounds better - migth be just me who was confused 
my A2000 keyb has rubber cups. The break was the caps breaking in two... top part + a small part staying stuck in the stems. The gluing problem I had/have is to get the caps back on without messing up the cups or any other bits (I have big fingers... so slightly clumsy)
All in all might be worth a shot buying a cheap/broken A500 (pm if you have one, I'm in the UK..., obviously any offers for a full A2000 keyb are welcome to)

I've removed broken key stems before by drilling into the centre of the stem (no more than 2 mm) with a fine drill bit, 1mm, in a low speed rechargable drill, and then screwing a fine screw into the hole. Once the screw is inside the stem nice and tight you should be able to carefully pull the stem out with the tighly lodged screw using a pair of plyers.
Don't drill too deep or you will stuff the keyboard totally. To see how deep you can drill pull out an unbroken key to see how deep the key stem is. Use some tape on the drill bit at the right depth to make sure you don't go too deep. The screw has to be a nice snug fit in the stem hole. If it's too big it will cause the stem to swell/stretch and you will never get it out.
