Is this a good deal?

I am thinking on getting a new camera for the holidays and I noticed a price drop of the Nikon 1 J3 at Best Buy the other day. It has been the camera I have always played with because I love its ability to do depth of field. I have a Nikon Coolpix P510 and I am thinking about selling that for $250 and getting the J3 for $299. But is that a good deal? On Ebay, someone sells it for $299 with an SD card, Lens Cleaning Kit, Camera Bag and 57 inch tripod. So, is it worth it? Let me know! Thanks.
