I use a set of surgical loupes. For smd work you need 3.5 - 4.0x, but
the major problem with cheap ones is a very small depth of field.
I have a sec of Galilaen loupes marked 3.5x, but are really 2x. They're
good for general work. Once you get into 4x, you're into Keplarian
loupes. I have a set of 4.0x with about a 1cm depth of field that
were pretty cheap; I'm looking to change those out.
The loupes are nice; you get binocular vision and 16-18 inch working
distance.
