[QUOTE="Ebenezer, post: 1806130, member: 24565"] I bought a used one. I can give you the name of the business if you'd like. A friend in KS bought one from them since I did and is also pleased with their purchase. You want a mechanical stage so that you can turn knobs and see the grid patterns (up and down and then move over and repeat via down and up..) quickly. Otherwise it would be a hard effort. I can look at the power of the lenses I use but I think it is 100X. Get a light under the base to see the best. I mix samples in disposable plastic drinking cups, use a home mixed Epson's salt solution and use the glove as a sample holder. It is basically cheap once you get the microscope and slide(s). The trick to speed for me is multiple slides. You can get several, set up the samples in that #, do the time to place samples on the slides in the same #... It speeds the process for me. I bought the ones with the green lines as somebody told me that the lines remain visible longer. The choice in microscopes is binocular or monocular. I surveyed for nearly 40 years and got used to using one eye. A binocular microscope is harder for me at times. I want to try a monocular to see if that is better. Try to see if a science teacher at a local school or tech center will let you try them before you buy. [/QUOTE]
