Love my Weber...going on 12 years with only a replacement of grates & starter. That being said, I just started using GrillGrates, which are aluminium grates which sit atop your existing grates. Aluminium heats up fast, and leaves gret grill marks, but the real benefit is the bottom of the grates is solid with holes for juices. The close bottom surface gives a very close heat element, rather than simply hot air from the gas jets. It does a great job of searing meat without burning, but more importantly it prevents flare-ups with greasy/oily/fatty foods. My first go-around with burgers & they were claimed the "best ever" by my family.
I have no relationship with the company...but it does up the quality of your grilling.
