My advice, having tried and used many scopes would be to buy used, either a Leica, Zeiss, Olympus, Nikon. If you want it new, try a Lomo multiscope. While the initial investment would be higher, the overal satisfaction will be better. Amscope like many others has a very limited number of attachments, the construction quality is dubious. You could soon want phase contrast, darkfield, oblique illumination. You could be wanting to collect different objectives like apo's, you will be wanting compensating eyepieces for those. You will be wanting aplantic condenser with high ap like 1.4. Who knows an attachment kit like a rotating stage with polarisation etc.
Don't be fooled with cheap microscopes, the advantage of buying used good quality would be if you sell it, you'll get back most if not all of what you have invested.
