Why do you want an over the range version if you don't have an oven?
I have a kitchen aid convection microwave and a toaster oven. They take care of 50% of my range cooking/ boiling needs and 85% of my oven needs.
I can't see the price, but be aware the cost for work on mine for new micro element and fix. Broken fuse for the display was $250 after 6 years of use.
Check out the Sears outlet centre. Scratch and dents with a store wide sale are a great buy.
