quest 2 if youre ok with cuckerberg and want wireless

index if you want base stations and a cheaper path to upgrade to full body

g2 if you just want to do sims

overall my bet is on the quest 2, elite battery headstrap, and a pleather vrcover. 

if you want to go high end and this has a consumer version https://youtu.be/gTwUTqyaU9I?t=136
get the index and sell the HMD later
