It will also be VERY difficult to sell because not only is there no warranty but Nikon and Canon may refuse (probably will) to repair it if necessary. Also, Nikon does and Canon may refuse to provide parts or independent repair facilities if they choose to repair. With Nikon especially and Canon and others sometimes, they are very adamant about stopping grey market. Its not only about the cost of repairing something they didn't get a piece of the sale on but also because their customers (the camera stores and department stores) that do play by the rules demand that they also observe the rules. If you owned Joe's Cameras or some other camera company that worked hard to get approved to sell Nikon, Canon or other brands and jumped through the hoops to purchase through authorized Nikon suppliers to maintain the proper credentials and Mike's camera clothing and liquor store opened across the street selling grey market (non-warranted or questionable merchandise for 25% less than you, you'd be demanding solutions from your suppliers too.
