Well if you do nothing else but put it in the dirt on a job and see what you think. It's free hours, and I think you will come away with a different outlook regardless of what you end up buying. Your spending 6 figures, might as well have all the available information. The ET 90 is, in my opinion, their flagship machine. Everyone has different likes and dislikes on how a machine runs. Me personally, this machine would be the one I would build if I had the say. It responds exactly as I want one to run. I wouldn't say that about their 5 ton machine that they just replaced, thankfully. Having one break down in 11k hours is incredible. I think you could run a handful of Kubota 80's to that many hours and not be that fortunate again.
