Zeiss D36 and Eschenbach 9870b - both around $125. I like the wide field of view and the option to go 3x or 6x or 9x. They have paid for themselves many times over by allowing me to discover hidden hairlines on proofs.

I use a Zeiss D36. I also like the ability to change magnification and the field of view. A friend picked one up for me, and I believe the price was $110.
Biconvex lens: Distinguised by two spherical (convex) surfaces. Used in large field, low power reading magnifiers. Magnification usually up to 4X.
Aspheric Lens: Aspheric curves allow higher magnification with less distortion. Used by holding the more convex side (side with imprint) towards the eye. Magnification up to 12X.
Aplanatic Lens: Consists of two equally strong plano-convex lenses. The convex sides are arranged face-to-face. Full image is clearly defined and free of distortion. Magnification up to 20X. (Magnification up to 4X useful for persons with macular degeneration.)
Achromatic Lens: Top quality lens. A color-corrected lens system that guarantees a clear, sharp image. Completely distortion free. Magnification up to 25X.

Yep, I use a 6x, and 12x for die minutiae, etc.

Maybe I only want 3 or 4X. Yikes, such decisions. Who knows?
Brent-Krueger Loupes
the best of the best
also have a large field 10x generic model works good for me
My very first eBay purchase was an Anco 16X wide field loupe (model 1020) but I rarely use it, since there is too much distortion around the edges.
