Product review (5 stars): Bertazzoni 30" stove
I have been using a Bertazzoni MAS30 4 GAS XT stove since July of 2010 and have had no problems with it whatsoever.
A couple of tips:

The oven door must be ajar to ignite the oven.
The oven temperature in normal mode takes about 10 minutes to balance to the right temperature. Mine is dead on.
Turning the burner knob all the way to the left will Not give you the lowest temperature. Watching the flame and turning it to the right to close to the off position will.
