Hey my name is Noah, I’m a beginner engraver and apprentice jeweler. I am trying to build a budget microscope setup for engraving and stone setting. I looked though the microscope list on the forum and have found a Leica Sz-4 and Olympus sz30 on eBay. They are both 200$ I just want to know if these are good scopes or if I there is another better budget friendly scope. The budget is 300$ for scope. Please and thank you!!
