We purchased the Frigidaire Gallery microwave to replace a 3 year old Frigidaire Gallery that we purchased as a suite during our kitchen remodel.
The newer model has a few improved features e.g. both +10 and +30 sec buttons. The overall design seems sleeker than its predecessor. The time display is more green than the Gallery oven display since it in a newer model, but that doesn't concern me, even though they occupy the same cabinet. It and the trim kit were difficult to find in Stainless Steel, so we had to purchase online. 
Overall, I am pleased with it but we did purchase a warranty for it. Hopefully it will last longer than the one it replaced.
