My personal recommendation is that you guys save some money and buy the real deal! A microscope for about 400-500 dollars and I can promise that you will NEVER regret it.
but if you want to start easy follow La_Hache_Es_Muda word and buy a microscope camera and use it together with a boom arm.
That was how I started in this business and when I got my first microscope I realized that I should have bought a microscope as soon as I started with micro-soldering.
