I recently acquired a used Borg Vintage OM. Here are some pics:

Excellent adirondack top (although I could easily live without the toner/stain that was applied to it.) Indian RW back/sides,ivoroid binding. Chrome waverly tuners.
Very fun to play, great tone (brighter than I expected), pretty decent sustain. Overall a pretty good value for the buck. I prefer this OM to the many Collings OM's I've played. Fit/finish/build quality seems comparable to Collings.
Used Borg Om's can be had at a good price....so keep your eyes open.
