ImageWriter ribbon re-inkers?

[lacoss@cello.gina.calstate.edu (LA County Outdoor Science School)]

Has anybody had experience they could share with me regarding re-inking 
of IW ribbons?  I've seen ads in old magazines for devices that do this.  
I'm not even sure if any of them are still in business.

We used to get our ribbons here at LACOSS for free from the County 
Office.  But, they have eliminated almost all of their IW printers in 
favor of LaserWriters.  Plus, they have changed the procedures so that we 
need to get our own office supplies (no more raiding the supplies 
closet).  Since I have been buying our own ribbons, I have started to 
notice how many of them we go through in a year.  Hence the interest in 
re-inkers.  Do these gizmos really work?  Does a re-inked ribbon last as 
long as a new one?  What are the costs involved?  Is the quality of 
output from a re-inked ribbon indestinguishable from a new one?  Sources?

Any help very much appreciated.   Greg
