"At first you might not notice much of a difference between a premium scope and a cheap Chinese knockoff because your eyes can overcome small defects, but you can get eye strain and headaches as a result. After long hours of use is where you will notice the difference between a quality microscope and a poor one. Optics are no place to cut corners. My advice: save your money and get a quality microscope."
What do you think of the Leica scopes? Can you hook up
A video camera to
One?
