Logitech G29
If DIY then anything is possible. can even use a half cut car dash board for the best feel lol.

Direct drive is a whole level of its own with 20N of force that is enough to break your wrist when you crash at 100% feedback. But most importantly the feedback is much quicker and stronger so you can really feel the grip level of each wheels way way better. However, fanatec is pretty over rated. There's a lot of much better and cheaper direct drive systems out there. But have to really consider getting the full set and solid aluminum anchored rack. the feedback is strong enough to flip an ikea table... that's why the entry cost to a direct drive can pretty much buy a car.

Most budget one is use your table. It's fine and works really well.

DIY is best if on budget
