I love my Fire Magic Echelon Diamond gas grill. Mine has the window, but I opted out of the remote control self opening top (Power Hood).

You didn't mention whether you need a built in or cart model - I have the E790 single side burner cart myself as well as a huge stainless steel hood since mine is up against a wall in a lanai enclosed on 3 sides. The E1060 is the biggest cart, and comes either single or double side burner. Or you can get the equivalent built in unit if that's what you need. You can see them all here:
