Have any of you ever bought a used lens from KEH that was rated as "Bargain" grade? I was wondering if this was worth considering. I have been frequenting their site for many years but have never bought a used lens from them. You can save a substantial amount of money buying a Bargain grade lens - in the neighborhood of 25% under the cost of an EX or EX+ lens.
They describe these lenses as having higher than average visible wear, and minor dust or glass imperfections that "should not affect image quality".
