I purchased my first Weber Kettle (18" silver) for a backyard party shortly after buying our house. Wife wanted gas grill, but I wouldn't budge. I had no idea about the bottom vents (grew up on propane). Took forever to cook, and the guests were starving. One of those things that people remember, and I don't mind one bit. Still not buying propane, and 3 Weber products later I don't regret holding my ground.
