A much easier solution to the wobbly joysticks is to simply slice the joystick springs in half. This is what 1281 did to our main drive joystick this year. This increases the spring constant, which greatly improves the 'feel' of the joystick.
Warning: Do this only if you have a spare joystick to fall back on. This may also decrease the life of your spring since you're asking more of it than it was designed for.

Personally, I find that it isn't so much the floppiness of the beige joysticks that is a problem, but the lack of feedback. With a good joystick, if you put it in any given position, there will be a force on your hand indicating the direction to centre. With the very weak springs in the KOP beige joysticks, that force is very small. Cutting the springs or adding brace elastics or something similar increases feedback greatly.

Other options:
-Find ANY other gameport joysticks
-Find a team that participated in 2003 (stack attack) or earlier that has spare joysticks, because the black ones included in the KOP pre-2003 were awesome.
-Ebay, ebay, ebay.
