Two other retailers that sell used equipment, both with an online presence, are B&H Photo, and Adorama. I've never actually dealt with Adorama, but I've bought both new and used equipment from B&H Photo. The down side to both of these retailers is that they deal primarily in new equipment. They do offer some used equipment, but nowhere near the level of merchandise of KEH. Like KEH, they use a grading system to convey the quality of their used products.

So here ends our lesson. By shopping around your neighborhood and on the Internet, you can find a great deal on an almost new camera. The money you'll save buying used can be spent on a better model, or invested in other equipment, like a flash meter or light unit. Good luck and good shooting.
