Advice on Buying a Microscope
I'm looking to buy a microscope for my girlfriend for her birthday. I'm basically looking for something that she can view insects and leaves and stuff through. Not exactly sure what kind of magnification would be required for that? I've done a little bit of research and from what I've heard a bifocal lens might be the way to go.
Are there any brands I should seek or avoid? I don't really want to spend a fortune, ideally under $300. Are there any other things I need to consider? I was thinking of perhaps buying a 2nd hand microscope from a school-lab if it would be suitable.
Any help appreciated.
