As in one of your last videos you tested Simracing gear from temu, I think it would be great to look at a aluminium profile rig from there. It is from a brand called minneer, and retails in germany for 200 euros, for just the frame. For an additional 150 euros I think you can get a seat from the same seller too. The rig is made out of 3060 aluminum profile, not the normal 4040 or 4080. As I think a lot of the community is looking for a low budget simrig, it is important to look at some alternatives. Unfortunately I can not paste the link here, but If you search Minneer aluminium profile rig there and see one for 200 euros, you will find it.
Have a great day!
