gotlogos,
Now that I look around at Amazon.com, these
look pretty good too for under $30.00, come with 4 different magnification strengths, and are lighted. That lighting would be a big advantage when looking into holes like our e-cig stuff has.
Tim.. Found the same set at Habor Freight for $9.99 Luv these 'cause you can change the magnification. Also they are the lightest ones I've found.
