I bought a nikon 105 micro f/2.8 AF lens from KEH. I paid less than the lens has sold for on ebay (using the completed auction search) and the lens is immaculate. Service was excellent (Arthur was my cust rep), packaging was fine and dandy and the lens arrived right on time. In as much as we all tend to look at ebay first, you might be surprised if you compare it to KEH. When it is important (this lens was bought for a job shooting rare books, sheet music and maps) and you can't swing new, KEH is an excellent choice.
