I have that mini-microscope as well and like it too. As far a lighted loupes, there is no reason not to have one as you can get a cheap one for about $6 on Ebay that does the job.

After while you will probably find yourself not using these things unless you know the blade has a pit or some other problem. Initially they are very good to have but you still have to learn to interpret certain things.
