Jorge,

Have you looked into Optical Inspection Stations (i.e. Camera with up to
100X, Monitor (color &b/w).

I've used this with great results. I suggest a combo Color/B&W monitor
becuase there are conditions observable best in both modes.

There are systems available for as little as $500 up to the Thousands.
