I have had a Mercator illuminated magnifying glass on a stand for decades. It is well made in every respect except that the lens is so misshapen that it is tiring to look through. Jaycar and Altronics have similar devices for about $110. Those of you who have one, are the lenses any good? If you move your head from side to side while looking at, say, a circuit board, do you get a rippling effect? There is nowhere locally that I can see one before I part with my money, and your advice would be valued.
Thank you
