I have had a stainless char-broil for 3 years now and it has been outside and uncovered since new. It got hit by a tornado and both doors and handle we're ripped off. I welded it all back together and it works flawlessly. One burner is starting to show signs of not burning properly but could possibly just be dirty. I'm not saying its a great grill but if it lasts another season it will only cost me about $50 a year.
I am kinda excited to see it go just so I can upgrade to a charcoal grill/ smoker setup. I have been debating building my own but have yet to decide if that is a economical solution or not.
