I have an old weber in the 26/27 inch area bought in 1986. The only problems I have experienced is the burning of the wooden handles because I experimented with a combination of splits and lump charcoal (replaced) and no chrome left on the grid. I need to find a low cost stainless steel grid. The PK has been around a very long time. Like the old reliable Ducane grills of years gone by, the body is cast aluminum. The only downside is the aluminum can be reactive to acidic sauces and such creating pitting. But while annoyingly ugly, it is minor, and should last a good long time.
