I would buy used from B&H when I am in the store and can see it in person. I bought a Contax RX from them that was used, listed as Factory Reconditioned, 8+. When it arrived, there was a tiny dent in the top cover, and the bottom cover exhibited significant brassing. The price was good enough that I didn't push the issue too hard with them, but I was unimpressed. I also had a salesman tell me once that they could only ship to me UPS, when I had ordered plenty of other items from them and had them shipped FedEx or USPS Priority Mail. I've had other things that I bought though, that were more in line with what I would expect from KEH - ie, like new, in box, had no idea what was "used" about it.
