I’m looking for an inexpensive but not crappy USB microscope as a gift for my nephew (age 7). (For those unfamiliar, this is basically a USB-connected video camera arranged with lenses that lets it act as a microscope.)
Googling presents an array of such devices. The cheap ones are really cheap ($50) but I’m somewhat skeptical that these will produce acceptable results. OTOH, I don’t want to spend hundreds.
Anyone have any useful experience here?
