Digital microscope recommendations


I'm at a point where I am concerned about the wear and tear on my Lyra Delos, and would like to check its condition through a microscope. Does anyone have a brand/model they can recommend at a reasonable price? Also, what am I looking for? Is any possible damage so obvious it doesn't need an explanation?

Any advice would be greatly appreciated.

Some models are $150 and they go on up. The one that I use is $550 and it's used in a lab.

Thanks for that URL, Pbnaudio. It partially answers one burning question: how much magnification is "enough" for examination and photographing of styli. One set of photos on the page specify 80X, to get a pretty good side view of a stylus. In another set they used 200X to get a very close up view of the working surface of the stylus tip. This tells me that anything more is superfluous. Does anyone disagree?

Hello,

Have you used the digital microscope to peer down into the record grooves yet? Let us know what you see in the groones. It would be interesting to hear what you see if you did a before and after cleaning view of the record grooves.
