I have been using the same grill for over 25 years. It is a MHP with all aluminum housing. I replace the burner and ceramic stones every few years and am due for a new grate. I is a very simple but durable grill. In the summer I use it 4-5 days a week.
I have natural gas (not propane) burners and ran a line to the back of the house. I have cooked lots of thanksgiving turkeys and one year the propane gave out mid cook. I switched over and never looked back.
I also built a tandoor oven for cooking naan and kabobs.
