What is in the high ball upgrade kits? I see one for a measly 8.95 on groovy game gear's website. I love my trackball, in fact it's about 75% of my social gaming right there!
I have an ultimarc u-trak trackball and doubt the groovy game gear package would work, but if I knew what was inside I bet I could figure it out or come up with something comparable. I would consider replacing my trackball but don't want to go through the hassle or expense of recutting the wood and brass!
