I purchased a  Signet 320 in late May 2017. I like that it features a solid, cast aluminum firebox and hood. The burner design is excellent and the grill heats up very hot, very quickly and holds that heat. Howver, after less than 2 months the stainless steel "flav R wave" heat tents are already completely covered in surface rust as are the stainless burner tubes. The grill is outdoors but covered. It's a good grill overall but hoping the stainless components dont rust out too quickly.
