I bought a TRF201 this summer and I'm very happy with it so far, though I have very little time to go to a track with it. I have to admit though, if the Durango would've been released earlier I would have definetely bought that instead.
I have a DEX210, but it's currently on the shelf

I can't afford to run two, but I also couldn't afford not buying the DEX210, it's too nice a car for that. That's also the reason I know I would've preferred a DEX210 over my TRF201, the building experience was amazing and the setup options on the car are endless
