Be aware that Amscope build quality isn't amazing. I bought an Amscope with an articulating arm. It seemed nice to start, but after a few months, the joints no longer hold the microscope head level. This isn't terrible for viewing with your eyes, but it means I can't set up the camera flat to a board. I have no experience with Amscope's boom arm or these little scopes.
Also, the adapter ring for the LEDs comes in two varieties. The first that I received was plastic, and the cast threads could slip straight in and out of the mating threads on my barlow lens. I ended up returning it for replacement, and received a metal adapter with properly cut threads.
I'm not saying that you shouldn't buy amscope. Rather, just expect that you might have an issue or two crop up.
