The best advice I can give when shopping for a grill is to take a magnet with you. Anything that the magnet sticks to, just imagine it rusted because that’s what it will be in a couple of years. The grill I bought from Costco (don’t remember the brand) only had ferromagnetic metal in a ring going around the control knobs. So far after around 5 years that is the only part showing any signs of wear.
