I have a bunch of kinds. I almost sorta collect them.
Get you a Bosch and Lomb, Hastings Triplet, 7X, folding magnifier.
Fits in your pocket, easy to use.
Go ahead and get yourself about 50 more magnifiers in every size and shape, from headsets and goggles to big desk magnifiers on a stand! The more the merrier. Magnifiers are cool!
But wait n see if you don't hunt down that little B&L when the chips are on the table.
More magnification is not as easy to use. Less loses detail. 7X is just right, and a Hastings is the best there is.

PS The American Optical model 60, is obsolete now.
Once upon a time it was a research grade microscope. But then newer models came out. So it became a college scope, etc etc.
But they are genuine real live microscopes you can actually have. Not a toy (which never did work) but a genuiiiiine working microscope.
And they are right at the edge of free when you find them!!
I got one for 10 bucks one time
Look for them, AO model 60
