Agree. As I think LMichaels said, the grate is the surface you actually deal with when you're cooking. It's one of the more important parts of the grilling experience in my opinion. I like the Genesis 2000 so much because I can do zones and it does have even heat output, I'm still not used to having no "hot part" of the grill. That said, with subpar grates it just sullies the whole experience, even if you do have a "hot part". Recently we were at a family friends' house, and they asked if I would grill the steaks. They had a tin can grill with a grate that felt like a flimsy cookie cooling rack or something. It was so bad that I rehabbed a 1000 for them, complete with cast iron grates. They are impressed with the Genesis, and have already said how much better it is than their old grill. But cast iron grates will give you that sturdy feel when you're handling your food. Same with RC rod grates, which I currently use. I like the stainless because those grates are burly like cast iron but easy to clean with the chargon, and I know that they will never rust, there will never be any damage to them due to how sturdy they are, and the quality of the stainless. Anyhow, for any other parts like burner tubes or flavorizer bars, I personally have no problem with less expensive options, but the grates are where, for one's personal grill, I would advise being a little spendier.
