Is it worth it to rebuild my trackball?

I recently fixed up a trackball that was acting up.  The symptom was a jumping effect.  When moving, it woudl skip back visually.  First I replaced the sensor electronics, and nothing changed.  It turned out that the metal wheels were slightly warped (moved a micrometer left/right while spinning).

To straighten them out (which fixed the problem) I used needle nose pliers while rotating them, bent them back and forth until they were straight.

Just thought I'd add this to this thread as I was about ready to replace the whole trackball myself not knowing what the problem was.  I thought it might be the bearings seizing up or that it might be the electronics, but it was just the metal wheel not being true.

DEFINITELY 3 in 1.  WD40 will just gum it up after it dries. 

Check out Bob Roberts site on breaking in new bearings.  I do the same thing with used (though he says not to do it).  I believe it helps to loosen things up more to spin the used bearings.

If the shafts are too badly worn you definitely should rebuild.  The price you're being offered sounds a teensy bit high.  Check Bob's page and see how much he's offering it for.
