A:Answer$200 but DIY is relatively easy.
Built a small little stable sturdy table at height of the oven. Placed/slided my old one on it to be hauled away and let the new one place on the table. Saves you ruin your back.
If cabinet sizes are same is just connecting 4 wires and screwing few screws in.
DIY scale from 5 likely a 2.
Good luck.
