I made my own cockpit, it's displayed somewhere on here. I would say it works on a scale, the better the cockpit, the better you will perform. Mine has a little movement in it (side to side). I imagine the professional builds will be very tight and more ergonomically designed allowing the user to concentrate more on the driving aspects. Mine pulls up to my big coach and allows for easy reach of the beers. Go with what you can afford and enjoy it.
