Hi Pat,

    Before you spend a lot of money on one of these microscopes I would
    suggest that you get hold of one of the little 'wireless spy
    cameras' such as the ones on this page 

    http://tinyurl.com/33wyuu 

    and play with that. I use one on my little cnc miller to see what is
    happening round the back of the work and, by loosening the little
    screw which locks the lens in place, you can focus down to about 1/2
    inch or so and get a high magnification. However, the reason I would
    suggest this is that you might find it is not suitable for what you
    are wanting to do with it as such a system necessarily presents only
    a flat picture (2D) and so you cannot get any good perception of
    depth of field. I initially thought the idea might be useful in my
    watchmaking and might provide a way to rest my eyes a bit but I
    quickly reverted back to my binocular microscope as the flat image
    didn't really give me a clear idea of where my hand was in space..
    Of course, it might work for you and then you might find that these
    cheap cameras are a more economical way of achieving the same ends.
    (while the cameras are basically intended for wireless operation,
    some of them can be used with a fixed wire which is how I use mine
    to avoid motor interference on the signal but they all provide a
    composite video output which, in my case, I have linked in to a 7
    inch LCD screen salvaged from an auto scrapyard - either a GPS
    screen out of a high end car or an 'in-flight entertainment' screen
    from a coach) 

Best wishes,
Ian
