I picked up a 135mm El-Nikkor last year for I think it was about $75. It's the old style lens, all metal barrel without illuminated f/stop markings. It is in absolutely gorgeous condition and makes very sharp images with good contrast. It is much better than the old 135mm Schneider Componon f/4.5 that I'd been using previously. To be fair, the Schneider has a fair amount of haze between the elements and would benefit from a good cleaning.
