tips on buying a microscope, looking for aa good used deal. ecoli, parasitesl, arva eggs,
ebay has new ones of a chinese brand, have to look up the name, but prefer used for better deal unless people know that the new ebay scopes A??? are a good deal. are scopes up-gradable , meaning, could i get a scope and add the camera attachment later?
thanks, pure noob here, i know i dony want clips, and i know certain lights = cheaper from my research.
