Thanks, Eric! I am sure you noticed that most of my reviews are from 4 years ago. Prices and availability have changed a lot (and keep changing), though some of the major players are still in the game. I am most sorry to see Dave Santana find that he currently cannot compete realistically in grates. (He still sells other excellent grill stuff, and if you are willing to pay big enough, I think he will still make you a set of grates.)
I have tried to add a couple of noteworthy newcomers since my first review, Qlimetal's 9mm set being the most noteworthy. If anyone has other grate sets you think should be looked at more carefully, please make suggestions!
