I have 4 Weber products at the moment and wouldn't trade any of them.
The Weber Performer is awesome because it's a 22.5" charcoal kettle fired by propane. The propane lights the coals and once their lit, turn the gas off and you're good to go in ~15 minutes. That's the same amount of time I would wait for my gasser to heat up the grates.
When I'm done, I shut the vents and an hour later the coals are cold. I shake off the ash and leave the cold coals in for the next cook.
The performer is expensive, but worth it in my opinion. Plus the side table, charcoal bucket and bottom rack make it the perfect party grill.
Gotta do it. My parents have 2 Weber Genesis II grills...1 LP and 1 NG and they love them both. The NG grill fell over during a storm and the lid broke. Weber replaced it for 50 bucks or so and it was at their house in 2 days after ordering it. That grill is 10 years old.
Stay away from the stainless monstrosities (unless it's a Jenn-aire...). I've had 3 in the past 6 years and dumped them all for Webers.
