Waited 5 months for delivery.  Rep kept estimating delivery month by month.   Unfortunately, it appears that Frigidaire is the only maker of a 27" wall oven/microwave combination. 

Thermostat is off by 25 to 30 degrees.  Oven preheats to desired temperature or above, and when item is placed in oven temperature drops.  Per the instruction manual, we set the desired temperature to 25 degrees above desired temperature and it does seem to maintain the desired temperature.  Temperature calibration does not seem to have an effect.
