Here is an example: sears.com/shc/s/Compare?5&partNumber_1=02282153000P&partNumber_2=A093758123&partNumber_3=02281993000P&prodCount=3
The differences between the three I selected:
1) The most expensive has steam clean and air fry, with True Convection
2) The mid-range one has regular self clean with Convection (not True Convection), with larger 9.4" element
3) The lowest price has regular self clean, and does not have convection, with lower bake/broil element wattage
There are differences in dimensions as well. (I only see two stainless steel ranges with Induction and Convection.)
