Shopping for appliances is not easy.
For my recent purchase, I looked at wirecutter as a starting point and bought from Costco. Also I got a 3rd party extended warranty (since you never know with water-using appliances).
According to Wirecutter (NYT): "If you’re a member, Costco offers the cheapest delivery and installation of the big national chains, you’ll get an additional year of warranty coverage for many products, and it will help you make warranty claims with the manufacturer."
