Carol, I have had almost every gas grill under the sun over the years...
The best, by far, I have ever had is a Weber...
Have had ours for 10 years now, and it looks as good as the day we bought it, and performs like day one still...
We have the same one on LI, pummeled by salt water spray constantly, and we have to replace the burners maybe every 5 years...
but with the Stainless Steel grates, that is all we ever have to do...
