Pocket Microscopes

I've seen a few pocket microscopes going on policebay would a 30x magnification be alright for trich inspection?

I have heard that's how some people do it (30x). However a pocket microscope is 8 dollars at Radio Shack and varies I think from 40 to 80x, and you can take pictures with it, or I should say through it with some popular cameras.

I couldn't find it at Radio Shack. I ended up having to buy one off ebay.
Get at least 30X's or stronger.

30x lighted pocket microscope is perfect!!
