What microscope should you buy?
It depends what do you plan on looking at and what type of microscope do you want? Also what quality do you want as in what magnifications will suffice: 5X, 10X, 40X....Typical light microscopes can go up to 40X but many of them costs above $1000.00 dollars and require microscopic slides and usually squishing the organisms. If you want to look at organisms live, you may want to to get a dissecting scope which can cost up to $900 dollars. Any microscope below $500 is useless. As for electron microscopes, they cost up to 1 million dollars and are only used at Institutions (or if you're a billionaire then go right ahead), they also require a constant water supply to the electron chamber and a critical point drier and gold sputter to prepare the specimens.
