I didn't think of looking at commercial microwaves so I ended up getting the Breville Smooth Wave [1] with its power and time dials. It's ridiculous that the only consumer microwave I could find locally with dials instead of touch controls was also the most expensive one with the exception of the ultra-sleek high end cabinet mounted units.

It's 1.2 cu ft which is on the bigger end and much quieter than the microwaves I'm used to with some sort of ventilation system that keeps going until you've retrieved the food. It's definitely more precise than the cheaper commercial microwaves I've seen without losing any of the "smart sensing" features, if you care for those.
