I bought my Weber Genesis 3000lx new on 8/15/99 (no craig's list back then). Since then I have replaced the flavorizer bars with a SS set from ebay. That is the only repair/improvement I've made in 14 years. It doesn't get near the use it used too since I've switched to lump, but she's out there ready for a quick burger or using the side burner for something too smelly to cook inside.
