Neco Mixed flow dryers? Looking for first hand experience of pros and cons.

We are looking at putting up a 24150 with the expandable feature going from 8 tiers to 16 in future. Is there anyone out there that would never get one again? I talked to an agi rep about the advantages of this dryer over a grain handler and he said the biggest one is, is that the controlling of the heating and cooling zones. We will be drying Wheat and Corn primarily. I Know a lot of neighbors having excel and grain handler dryers but we have agi bins and agi suretrack and like that platform so that is our reason going this route.
