io2redactually, most products are poker2 or even poker1, charges around 400 rmb on taobao.com. They sellers just use poker 3 pics, when you place the order, you have to choose specific model and then you will see poker3 will normally be out of stock. options left are poker2 and poker.
I donot think taobao is a good choice as vortex is a taiwan company and I have not found any shop running by vortex on taobao.
