I've still got my GH3 which I bought new during an Amazon Black Friday sale, after the £200 cashback it cost me a net £275, I always felt like I stole it. It's a lovely camera and it's size and weight mean that it is well suited to longer lenses. I added a battery grip which holds a second genuine Panasonic battery, it's possible to shoot hundreds of photos in day and never get close to running out of battery power. The menu system is so much better than the EM1 which I also own. I find the GH3 exposes better in bright light but use the EM1 in low light which has the aid of state of the art IBIS. The GH3 is much better for video with the flip out screen, clean HDMI output for an external monitor and both headphone and mic sockets. It's unlikely I will move mine on and at current prices they could be a sound used purchase with one proviso. A lot of the GH series have primarily been used as video cameras so a low shutter count is a bit meaningless on these cameras, they may have had a lot of wear and tear, so it makes sense to buy the best possible condition available.
