(Ed: You can start with post #66 if you want to see what I picked for my first scope.)
40X-2500X LED Trinocular Compound Microscope w 3D Two-Layer Mechanical Stage
$225 (on sale) seems like a great price. And it seems to have all the necessary features.
But they have so many similar models...
A few weeks ago my microscope broke. It wasn't as old as PaulB's relic (I think he calls it an antique) but it was several decades old. So, I was then overwhelmed and excited with all the new options out there today and got a trinocular microscope with a 5MP camera. 40-2500x. Much stronger...
