I use an intel microscope that connects to my computer. It is made for kids but works good enough for me and is easy to use. Also I can view things right from my computer and save them as pictures plus edit them later. I paid 60.00 new a few years ago but you can proably find a used one on ---- cheaper. Here are a couple quick photos I just took. It has a top and bottom light and 10x, 60x, 200x magnification. These could have been a little clearer but I was hurrying.
