My suggestion is a Weber gasser, and for these reasons: My dad just replaced the Weber propane grill I grew up watching him grill on and learned on. This thing is probably 30 years old, and is still working, as we took it to our lake house. It was a three burner and he wanted a four burner. But, the other point, he has been able to replace various parts because of the way Weber supplies all these parts. Easy to keep it up when needed.
I also have a Weber propane down at the lake, its 15 years old and still kicking! It’s at the lake because I built an outdoor cooking area and have a built in Bull grill now.
There are plenty others, but what is your budget? And what are you looking for in a grill? 4 burner, side burner? Rotisserie? Searing station?
I’m also going to recommend you check out Amazingribs.com due to the large number of grill reviews they have on completed on their site. It may help you in your decision.
