microscope

I've never used one before is the one on this link what I need?

RadioShack.com - Cables, Parts & Connectors: Tools & soldering equipment: Magnifiers: Illuminated Microscope

Thats the ticket!

60x-100x is way to much you are looking for a lighted 30x pocket microscope.

That will not provide you the proper field of view to harvest on the average.

I went to Radio Shack yesterday and saw the very same microscope, but so 60x is going to be too much huh ;/ I need to find something that'll work

That microscope works fine, you might need to move it a little to get a clearer idea of a larger area, but FOV isn't that important for this application - the surface area you are checking is not that large anyways. 100X you'd hardly use though. I mean if they have a 30-60 that is the same price go for it, but don't stress over it. Just sample from a couple of different locations. I have used/am still using that exact microscope for going on~ 6 years or so - Don't fix what ain't broke!
