I typically am kind of a computer geek and am pretty analytical. But, for some reason I have never really felt the drive to get an Auber.
However, depending on the price and ease of install for the retrofits that are supposed to be coming I am going to be in a quandary about whether it really means enough to me to add this on. The cost/benefit analysis will ensue.
If I would have recently purchased a new smoker without it, I honestly would not be that bummed. Like Tony said, the Auber users are not going to be able to produce any better product.
The key benefit as I see it is to be able to schedule the program to make the smoke for set times and temperatures and move to resting mode at the end of a smoke to make it even more "Lazy Q".
I don't worry about smoke box temp anymore and only probe it if I am doing a single piece of meat and have an unused probe from my Maverick. The swings just don't bother me and don't affect my smokes.
The closer temps do have a benefit when smoking fish and jerky where you need to keep temps below certain temps. But that is the only time where the temp swings could be a problem.
The bottom line is that both the traditional models and the new "D" models are top of the line and really beat up on the competition.
