There are so many gas grills on the market that are made by someone else, it's hard to know who will stand behind it. I live on the water in Florida and the salt can reduce a grill to a rusted hulk, in a matter of years. With that in mind, I decided to step up and get the 620. It's not all stainless, I wish it was. I have used it 2-3 times a week for three years now and it still looks and works great. I recently noticed, while cleaning the unit, that a few items were rusting out. After a call and a few e-mails my warranted parts were replaced. She's now good as new. One facet I really like about this grill is it can get really hot. Easily 650 + degrees, which is great when you're grilling steaks. BTW, this grill is also made in the US... something to think about.
