I'm looking at USB microscopes at Dealextreme. There are two that I am looking at.
The first one is 20-200x magnification and 2 megapixels.
The other one is 20-400x magnification but only 1.3 megapixels.
I pulled out an ancient Tasco microscope that I got when I was a kid. The edge at 150x magnification seemed to show all sorts of detail that would be useful. I'm just wondering if the trade off of more magnification at lower resolution is worth it. Thoughts?
Edit - I just noticed that the 20-400x scope is backordered. I went ahead and ordered the 20-200x 2 mp version. I'll take some pictures of the progression of the edge as I hone a razor.
