<p>[QUOTE=&quot;PEdoubleNIZZLE, post: 167951, member: 794&quot;]Radio Shack used to sell microscopes (not sure if they still do) that shone the light onto the surface rather than thru it, like a biological microscope. I had a 30X and I LOVED IT! Only $10, too.</p><p><br /></p><p>Also, the difference between a plastic $20 microscope and a metal $600 microscope is the resolution of the lens (cheaper usually plastic, more expensive made with glass with a higher quality control.) Generally at something up to 100X, the cheapies are okay to use.[/QUOTE]</p><p><br /></p>
