I'm looking for a large format (24 X 36 or 36 X 48) digitizing tablet
(such as DrawingBoard IV, Super L III, or Summagrid VI).  Anyone
have one laying around that they'd be interested in selling?
Or know where I could get one?

I've already checked all the obvious places, e.g. The CAD Store,
ebay, Google, etc.

Thanks.

Fritz
