Samsung VR Controller & S-Pen

Hi Guys,

Samsung has lived upto their reputation again. Gear VR 2017 model is exactly the same like the 2016 model but latter one comes with a controller and costs 5k more. So, I am looking for only the controller for the 2016 model. If the Sammy one is cheap and works well then fine otherwise I can go for the compatible one's also. Also I am in need for a S-Pen like device/pen for my non-Note phone. Can you please suggest some?

Thanks
