BH's set of mini-big-eyes are great! I had the opportunity to look threw them in the field this past weekend. It took a tremendous amount of self control to keep my money in my wallet. They are very compact and without the hard case, would easily fit into a backpack for field use. They are clear glass, focus and adjust width quickly. Also, when set at 30x you can see the gnats on a deer's butt from a looooong way.
