Dave - sounds like the wait was worth it. Given the fact that it is free, unless it is a total peice of junk, the only thing I would really worry about is the frame being solid. Everything else can be replaced. Nice thing about it being a Weber is that parts will be available from a couple of different sources. Hope it works out well for you.
