How cheap?
Do the optics work?
Are the bearings and rollers original?

A TB that age usually needs new rollers. And perhaps new bearings. If the optics don't work, you'll need new optics. And that yellow ball, how about replacing with a new white one.

Congratulations. Your cheap trackball just cost you a fortune and all you're really left with as original is the metal frame.  ;D

MinerAl:
What Ray said, but there is some hope if the bearings are salvagable and the rollers aren't too badly hour-glass shaped.  You can do some reviving of the bearings by soaking them in WD-40 for a good while and working any rust off of them.  If the rollers aren't too bad, cleaning all the wd-40 out of the newly de-rusted beearings and lubing them really well with 3-in-1 oil (or your favorite machine lube) will take a rough spinning ball a long way toward smooth operation.

Oh, and the ball isn't yellowed, it was never cueball white.  They are "cream" colored.

Take a look at the rollers, if they aren't too badly concaved then go for it. 
PacManFan:
I've got one of those too.

Get yourself some hex wrenches, and take the entire thing apart, clean it out,  get some silicone lubricant for the bearings, and run them with a power drill until you break out all the dirt/dust.

My 5" trackball is now the centerpiece of my CP.
