Thanks commoncents13! It is just an Epson Stylus cx4200. The software with it is quite good when you use 'professional' mode. Just starting to get the hang of scanning now. Different angle placement for lighting etc etc. A cent at that DPI would be like a 200mb file, so I zoom it in within the scanner software and scan the area I would like at that DPI then just save it as a JPG. I am going to try just going full tilt and then using something like Photoshop etc to sharpen and zoom the scans as I am sure the image quality will be far better.
USB microscope is what I will get next. Just doing some saving :)
