I see highly rated USB digital microscopes on Amazon for $20 and up. Unfortunately, I also have physical/visual limitations but my responsibilities to my family's finances must take precedence. I'm admittedly too bummed from disaster-disappointment, rinse, repeat syndrome to trust my judgment or anyone else but you guys so I'm hoping someone can offer their best suggestions regarding the Amazon products. Sorry. When I'm feeling healthy I ramble but I would truly appreciate any input. Best wishes to all, and thanks for your time.
