My dad had a Weber kettle grill that my mother kept for at least 10 years after he died, until she moved to an apartment.
After going through a number of gas grills ourselves for a few years, we finally bought this 18in charcoal grill, basing it on the premise that fewer moving parts is more when it comes to grills.  I can't even say how old it is, but it's at least 20+ years old. We've replaced the inner grill (grate?) a few times over the years, because that's what takes a beating. It will last forever!
