PSVR2 is so expensive :(

I currently own a PSVR and I really wanna upgrade to a PSVR2 however I unfortunately do not have 550-600$ to spend. Even if I decide to get a used one, that's still around 300-400$. I'm also wondering if it's even worth it since I barely use my PSVR already and the only PSVR2 game I really wanna play is The Walking Dead: Saints And Sinners - Chapter 2: Retribution which already has a PSVR version and that version of the game is also cheaper. I also mostly really want a PSVR2 for the controllers since the PlayStation Move controllers are not that great for VR games where you actually move around such as the first Saints And Sinners game. I don't know why they decided to use the Move controllers for the PSVR especially when they already had a blueprint for a VR controller with the Move Navigation controller for the PS3. Just take the Move Navigation controller and make whatever modifications and adjustments you have to so that it's compatible with a PS4 and PSVR.
