Interesting stuff, thanks for sharing, I've never seen one in person so it's good to read opinions from folk that have.
My two DFGT wheels I use for local multiplayer with friends are getting a little long in the tooth so I have been keeping an eye on replacements. Logitech have always been good to me so I was hoping to go with what I know! They've had a really tough life (they probably spend as much time bouncing around in the back of a real car as they do set-up!) and apart from a small incident involving a dog and the power supply they've largely done the job perfectly for what I need them for. I think they were £89 new when I bought them back whenever GT5 was a thing but I think they had a small store discount so may have had an MSRP here of ~£100. The UK is notoriously expensive for this sort of stuff though so I'm always conservative when guesing a second hand price.
It's not that the G29 is a bad wheel, it's just that the Thrustmaster T300 is a significantly better wheel at the same price (I've owned both and kept the T300).
It could be argued that the G29 is a more balanced package though, as the pedals are a lot better than the stock Thrustmaster pedals. It feels like most of your money is going toward the base (motor) with the T300.
Overall, the G29 felt like a wheel that was made with an inflated MSRP to be discounted, if that makes sense. At a discounted price - which I've seen at less than half of what a T300 costs - it's great value.
Being gear-driven does mean that it's a weaker and louder wheel than a belt-driven one (T300); it suffers from the feedback deadzone in the center, and has "chattering" (rattle) that is common with gear-driven wheels too (including the DFGT). But that's totally fine if you can get one for ≤$200 rather than paying $400.
Either of those wheels is excessive as a "starter wheel" just for playing a game like
Euro Truck Simulator though; which is why I'd recommend the DFGT here.
It's a shame Logitech didn't update them, or even continue making them without any changes. They were extremely good value for something with real force feedback, 900° rotation and a shifter.
