Howdy folks, just idly considering getting a sturdy microscope with good optics, good eye relief. I know there are a lot of toys out there, but I’m looking for something that will last. Any machinists, parts inspectors, etc. out there with some recommendations?

I found this, but there’s only one review on it:

I’m trying to keep it under $100, but feel free to post more expensive options too if they’re well-made. Thanks!
