I got them. I have the wok and chicken roaster. I have the cast grid and the cast pan coming. The chicken roaster can double as a veggie basket (the infuser can is removable). I haven’t done a stir fry yet but will soon. I enjoy doing everything out on the unit if possible. It’s just fun for me. If you are like me, I say go for it. If not, buy more meat.I have those grates, including wok, frying pan, beer can, unit, etc. on my Summit 670...just working on convincing myself I need it on my EX 4. On the summit I use over the three- burner center sear station, which is terrific with the wok.
