Motic DM-52 - 0.3MP Compound Digital Microscope ,$349

Three professional, parfocal objectives (for easier focusing) and a wide field WF10x eyepiece provide crisp images while a clever 'floating stage' makes moving the slide easier at higher magnifications. You can push the stage in or out, left or right or even turn it around. The LED light is rated for 50,000 hours life with illumination equivalent to a 20W tungsten bulb. The battery charger automatically stops charging when batteries are fully charged to prevent over-charging.
