I almost bought one, but I just couldn't say no to another Weber. Napoleon makes a nice grill and the warranty is longer than Weber's. No regrets sticking with Weber though.
I was telling my father in law to get the Weber, but he chose the Napoleon. I'm a tad bit jealous of it. It is a great grill, but a Weber is also hard to beat.
My brother had one for many years. It was great. It would stand toe to toe with any weber I have used. Not sure where they are price wise. I would lean Weber just because getting parts is really easy.
