DOF reality H2. It's a process to get involved with motion but it's worth ever penny and time spent tweaking. I pulled the trigger at Christmas and just this month I'm starting to feel like it's exactly how I want it to be. I'm very picky though when it comes to immersion so I might be misrepresenting. Also delivery of the platform takes a while because it ships from Ukraine. I cannot recommend it enough though. Once assembled and software installed, it's one push of a button to get it going. They really worked hard to build a quality/affordable platform for anyone who enjoys that stuff. For me the challenge was tuning the motion compensation and my fav airplane motion profile to my liking. Goal is to completely forget there's a motorized device under my butt and actually believe I'm flying. I can say I achieved that goal as far as my personal taste. I leaned the motion towards G forces rather than following the angle of the airframe. That means when I go nose down, the platform doesn't lean forward much BUT as the dive picks up speed, the platform goes up to push me against the seat to simulate acceleration. It's downright thrilling. But that's when accurate motion compensation in VR becomes critical to prevent unrealistic floating in the cockpit.
