"the scope" usb digital microscope

This was my favorite product at MacWorld. It is a handheld microscope from Bodelin that plugs in to your USB port. It comes with an interchangeable 50x lens with a built-in light for only $199. 1x, 100x and 200x lenses are available for $85, $99 and $129 respectively, and it captures 640x480 stills or video. Using a C-Mount Adapter for $20 one can use standard "C" mount microscope and telescope lenses, they told me, and a fiberoptic lens is on the way.
