This is our second GE combination wall oven and convection/microwave (2 houses, not a replacement!).  We love the oven's deep and easy to clean interior, as well as the sliding rack.  The Advantium oven on top seems intimidating to use - but then you give it a try and WOW - it is fabulous.  Faster cooking times, lots of preset foods, and it does a great job browning and evenly cooking.  And the microwave features are great as well.
