I work for a company that sells Weber gas/charcoal grills and we just started carrying a competitor to the Big Green Egg kamado-style cooker called Primo. The Primos are actually built in the US while the Big Green Egg is manufactured in Monterrey Mexico right now. They are essentially the same thing, but the Primo is on average about 15% cheaper. We just started carrying the Primos and I have limited experience with the Green Eggs, but I think the Primos are worth checking out if you're planning on spending $800+ on a grill/smoker.http://www.primogrill.com/
As far as Webers go, they are great grills. They by far have the best warranties of any large manufacturer of grills on the market and offer replacement parts for virtually all of their products. I have been selling them the last three years and I get nothing but positive feedback on them. They carry a premium, but what you get is a grill that will actually last more than a couple years and continued options for replacement parts/additional accessories.
Here are the warranties on their Spirit and larger grills...
