If the intent is surface mount work, get an old B&L Stereozoom 3. I'd suggest getting one with any attached illuminator, even a broken one, since the fitting to hold the illuminator is about $30. Later model stereozooms had plastic parts in the focus mechanism. If you need more magnification, you can always get "stronger" occulars.
