The Pibbs isn't digital... it has a knob for the timer and a knob for the temperature control (1-10 with 10 being the highest). This knob controls the amount of steam produced. The max time setting is 60 minutes. Umm... lets see what else ... oh, it has an indicator light to let you know when the water is low, and it also has a vent on the hood that you can open to regulate the amount of steam in the hood. I always leave it closed though. Hope that helps.
This helps a lot.
I'm waiting on Tammy from IBBE to get back to me with detailed descriptions of the other steamers I'm looking at. Then I'll make my final decision. Seems like this shouldn't be a big deal, but to me it is!
