Replacing GE Micro/Convection Oven

My wife wants to replace our existing 12 year old GE unit. Has anyone here installed GE's Micro/Convection with Advantium technology which combines convection with microwave cooking ? Like it ? Pros and cons ? I am looking at GE Model No. PSA9120DFBB. It will fit and looks like it cooks several ways...and fast. Thanks for any advice.
