It looks like a fine grill crankin. The only thing I couldn't tell (and probably because I didn't read the specs slowly enough) is if it has two sides that light up independently from each other. With this feature you can do some slow cooking and smoking with the side your food is on turned off. To answer your other question about grates - the cast iron grates are good for grill marks.
