I'm going to sell my GH3 with the battery grip and a couple batteries. Includes box and manuals. It looks like new and only has about 10-15,000 clicks. What would be a good asking price? I'm hoping for 350-400 but not sure. I also have a like new GX7 silver kit I'm going to sell. Guessing less than 5000 clicks on it. Value? Selling both these to get a G9 body.
