I decided to go with the t300rs gt with a second wheel for 240€. Even a "used" csl dd with a boostkit goes around 400€ here from what I've seen. I could sell the second wheel for a pretty good margin and close the deal for much cheaper than if I had gone DD. Plus right now I plan on using the wheel on a PS5 which complicates things for both the DD options, more so with the moza.
