I have been a KEH customer (both a buyer and a seller) and, overall, my experience with them has been very good. I have bought EX and better items only, as I tend to be careful about cosmetics. I thought the EX+ A-1 body I bought was pretty good; however, I returned it as it had a tiny amount of brassing. As far as I know, an EX+ body should be free of brassing. In the rare case where I have requested a return or exchange, it has, on one or two occasions, taken a while to be processed. I just did an exchange, and am looking forward to the arrival of my new items.
