A gas grill is just a bunch of tubes and an igniter that breaks. (I've never had a Weber gas, maybe those igniters are built far more solidly?)
I buy them 75% off at Target in late fall, along with stick lighters. They last about 4 years, then I put together the new one that's been sitting in the basement. If I used them for more than a few burgers, or snausages, or scrimps, I'd probably spend a little more. My opinion? Buy a used one if you need one now, and then shop the sales in the fall. Just opinion. They are just a series of metal tubes that carry gas. I've had 3 with side burners - probably used a side burner 2 times. I really like having a gas grill for quick burning up a meal in nice weather, or having the option to throw some real deal fire grill marks on a fat steak and lobster on nye, but they are just metal tubes that spit out adjustable fire. It's an outdoor broiler and a highly variable temp outdoor oven. Some look nice, but they do the same thing as an ugly one - spit out fire. I'm too lazy to clean mine well, so, I just buy them cheap, and know that I'm gonna replace it in 4 years.
