I haven't bought one in about six years. I've been happy with it and now need to buy one for a different house. I've been studying and comparing five different 800 stainless models on AJ Madison and am completely confused by the comparison tool not to mention some of the info is wrong - comparison says 42db but the specs say 46. And then what's the difference between digital pad, touch pad and touch sensor controls? And I know what condensing drying is but what are heated and vented and what's zeolith drying? And what's an adjustable third rack vs. a multi-purpose vs. silverware. Can anyone explain the difference between the models in a nutshell? All but one appear to have hidden controls and an actual handle vs. a recessed handle - that much was clear from the photos.
