I don't have a picture of my microscope, of course I can always get one. It's a cheapy from this little store on the west coast of Ca. I didn't get it for this use but better this then bugs. And yes it's machine doubling. http://www.cointalk.org/showthread.php?t=4446
I also use this scope that plugs into the usb port on my computor. I'm still playing with the lighting on it.
I purchased it on e-bay for about $80.00. http://cgi.ebay.com/Portable-200X-USB-Digital-Microscope-Video-1-3M-Camera_W0QQitemZ160269825689QQcmdZViewItem?hash=item160269825689&_trkparms=72%3A552%7C39%3A1%7C66%3A2%7C65%3A12&_trksid=p3286.c0.m14.l1318
