Do you think a 1998 Tracker manual window regulator would work on it?  Rockauto still has left door manual regulators listed 1998 Trackers for about $95.  IF it didn't work (but I'd bet it would) you could always return it.  They just didn't make a whole lot of expensive changes to the base vehicle.
I wouldn't buy a used one unless it was for $5.

I keep an extra driver's side window regulator on hand because that is the one window that gets used ALL the time on my truck.  I've replaced mine twice to date.
