This is what I’d prefer, so may just need to wait. Also I barely have time to game currently so this is probably just not a wise purchase for me atm.

Ah well, eventually.

VR playing people - how much space do you need to use it? I have a place behind my PC where i can stand and move my arms around with hands out (barely) but that’s about it. Feels like I should wait till i get a bigger gaming area to think about getting anything like this.

You can just replace the tops with a generic version and refill yourself. Takes two seconds and a vice grip. Did it for my mom, and got her a big food grade CO2 tank, and now she’s set for years.
