All of our kitchen appliances are Frigidaire products so when the time came to replace our 12 year old Frigidaire dishwasher we wanted to stay with a brand that we knew and trusted.
We chose the Frigidaire Gallery model because it offered outstanding quality at a very reasonable price. We have had our unit just over a month now and could not be happier.
It offers so many more features than our old dishwasher while still providing excellent efficiency. The two features that I find most useful are the sanitizing option and the max boost drying option. 
Overall, we are extremely pleased with our Frigidaire Gallery model and I would highly recommend you strongly consider Frigidaire if you are thinking about upgrading your current dishwasher.
