The grills are very well constructed. They state themselves weber grills are designed and crafted for the long haul. And its true. A buddy of mine has had his weber grill for over 10 years and it is working fine.
When you have a product like the summit gold 6 burner gas grills you have to damn near the best. These grills are just a thing of beauty. 902 sq. in cooking are, 57,600 BTW-per hour input. 12,000 BTW per hour input side burners.
Replacement parts. Part of the reason weber grills last so long is because of how easy iit is to maintain them. By simply following the steps on their website to find out which grill model you have. The parts are also relatively inexpensive. It only cost around 40 dollars for new burners or 45 for new cooking grates. To me that is a pretty good deal specially if you have had your grill for 5 years. You wouldn’t expect not to have to spend money on your 5 year old car would you? Well same goes for grills.
Webster is a personal favorite of mine. Webster gas grills are a durable well constructed grill with tons of features.
There are some important features you should be aware of when making a purchase. To properly broil a steak you have to deliver a minimum of 30M BTU's. But even with 30M you will have to close the lid to the grill and allow it to reach 700 degrees fairenheit before placing the steak on the grill.
