I have a couple of fully equipped benches with more tools than I can list, but the ones showcased below are the main ones that get daily use.
I'm using the Meiji EMZ-5 stereo zoom microscope. When equipped with the GRS Acrobat stand, you have a bright, clear, image with approximately 5x to 20x zoom range. The Meiji scope is made in Japan, and is a very high quality microscope that has become the standard of the industry for hand engravers.
I also have a Zeiss Stemi 2000 scope. They are great microscopes and deliver the quality of image and brightness you expect from one of the world's greatest optics makers. The down side is that they are extremely expensive, and probably tripple the price of the Meiji system.
I will caution you about one thing, and that is a microscope purchase is no place to cut corners. You wouldn't buy cheap eyeglasses that weren't clear and sharp in order to save money, and the same should be true with microscopes. The quality of the Chinese knock-offs is notoriously unpredictable and your eyes deserve better. Invest in a Meiji and you'll never regret it.
