For the money I don't think you can beat those Qulimetal 9mm grates. One of the things that separates those from the ones Rcplanebuyer makes is the lack of a third support rod in the middle of the grate. It's not a huge thing, but that extra support is just another place for grease and carbon to collect and makes it slightly more difficult to keep clean. I would just message RCP and ask him if he's still making/selling grates. If he is they will be quite a bit more expensive than the really nice Qulimetal ones.
