What is the best sim rig for under 500$ for a 12nm dd wheel?

Looking for a good sturdy semi cheap rig for a moza r12. I’ve been looking at NLR and other brands but can’t seem to find one that’s in my price range for a dd wheel. Maybe you all could assist me and help me find something. I’m at a loss. I have been using a cheap sim and an office chair stand but I need something with more stability. Thank you.
