We use the microwave/convection oven instead of the gas, which was an upgrade(!?) I'd prefer the cabinets!
The convection took some getting used to, but it seems to do a good job. There is definitely no relation to the double oven GE Monogram convection ovens at home. The RW's is slower than a standard oven in my experience. I will probably uprade it next year.
We supplement the convection with a halogen oven I picked up at Walmart for $29.95! It does a great job on some things that require higher temps for browning. I store it in the bedroom in the cabinet to the side of the TV, which is deep enough for it.
We also supplement the cooktop with 2 induction units. They are cheap and easy to store.
