And even with a dino-lite, optical microscopes will give much more control and resolution than a 5mp or less digital, but more money also. IMO.
I agree however .... I purchased an optical scope it was nice but huge! No place to keep it so I opted to go digital never looked back. In fact at that time the optical was cheaper as digital were new and cutting edge. The optical also came with digital cam. At extra cost of course.
