Query: Inexpensive Microscopes

One of the worst things people can do is sell someone a cheap microscope or telescope. Microscopes of this nature do more harm than good. The optics are plastic and extremely poor. The focusing is very course and very poor. The idea of using 750x power is very misleading, you need a lense with oil at that power. Get imformation on microscopes and buy a decent one. They are not that expensive new or buy a good quality used one for less than fifty dollars. Just don't but a cheap plastic miroscope. If someone has the interest don't ruin it with a bad microscope.
