I purchased a Baron S490 on 4/3/16. I have to voice the same displeasure as many other people.   These grates rust horribly.  I purchased this grill in hopes of not having to worry about things like this for a long time and it has taken less than a year.   I hope Broil King compensates us somehow because these grills are not cheap.   Again, I love the grill but the grates are junk!   Need to go with the stainless grates I guess.
