I replaced my Weber Silver Line from 1992.  26 years old and still going strong.  (The serviceman who connected the NG from the house to the grill, ended up taking my old Weber grill).   The main reason I bought a new grill was because I wanted to convert mine to NG.  Turns out you can’t modify a LP grill to NG.  Hence the “new grill”.   
No question about what brand I would buy again.  This grill is stainless steel which makes clean up easy. 
I do grill 5-6 nights a week all year round.  I live in the Northeastern part of Pennsylvania and winters can be harsh but I continue to grill outside.   Thank you Weber for making a quality product that I can count on.
