@ Framemaker- You can look into a naturescope Nikon microscope. You can find them for about $250-$300 new, and they are great for a basic field microscope. They are water resistant, shockproof, 20x magnification, and great Nikon optics. The biggest downside is there is no lighting included. The microscope does fold down into a compact microscope, and it should do the trick. I hope this helps.
