If you like the budget haptic rig for my father then check out my compact 3DOF motion rig, built over a decade ago specifically for VR and still going strong: https://www.xsimulator.net/community/threads/dx-compact-simulator.5866/

Plus even more extravagant DIY rigs, of all types: https://www.xsimulator.net/community/forums/diy-motion-simulator-projects.22/

Honestly you can get so much more bang for your buck, this is the VR haptic rig I built 6 years ago for my father with an Arduino and control board, with 10 SimHub controlled rumble motors (8 built in and 2 for peddles), and 2 X 50w transducers: https://www.xsimulator.net/community/threads/teddles-vr-haptic-rig.13821/#post-231405
