Please help me with Pimax 4k

Hello there.
I will be getting a Pimax 4k soon, and I already made a topic about this, but I would love to get some more help.
I am buying a Pimax 4k from a close relative, so I will only get the Pimax 4k VR, without any sensors or anything, so I was wondering what else should I buy on amazon or ebay or some other site to make the experience the best?
Can someone suggest me some motion controllers that are cheap and work on Pimax 4k? Also what else should I buy to make it more realistic and fun? (I will mostly use the Pimax 4k for steam games)
Thank you very much!

Also, is my pc good enough for the VR to work smoothly? My pc is a Windows 10 64 bit, 8 GB Ram, AMD Athlon™ II X3 450 processor, 3.20 GHz.

I think you can buy NOLOVR on amazon.

Or you can buy it on www.nolovr.com.

I can’t find only controllers, since they all come with the VR itself.
Also, would the Samsung gear vr controllers work?

Pls find on www.nolovr.com or you can contact them.
