What this guy said. You can get a AMscope, same quality and criteria for the same price as well. https://www.amazon.com/gp/product/B009N3QVV2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Every now and then one of these will go on sale for 280, i waited and got mine on the sale. I'd only go with AMscope or swift, haven't had any luck with lens quality from other brands.
I would not go with a binocular because it can reduce your ability to use a camera and the microscope at the same time.
The microscope me and Tomjbaker linked are the best deals. You will regret getting anything cheaper. Best not get one at all and wait till you have the money.
