I bought the Stok Quattro gasser in 6/2011, before Home Depot ended their "experiment" with them ! I've been pleased with the grill... Although it looks like crap now, that doesn't bother me...all my grills look like crap, because they sit out in the FL sun !

The gasser came with the insert removal tool, the veggie basket, the flat griddle, and the pizza stone. I've used the basket on the gasser, and the stone in my regular oven (for baking !)...like them both !
I had been looking for the 22.5" CI replacement grate for my Weber...last time I posted about it, it was hard to find...still available from the Stok web site, but always "out of stock". I forgot about it until just recently...and I was surprised to find that the Stok stuff is available both from Target (who apparently picked up the line), and Amazon ! I recently ordered both the replacement grill, and the wok insert, from Amazon.
To be honest, I haven't used the equipment on my Weber kettle yet...the CI replacement fits my kettle just fine...I suspect, as others have said, that the CI may be a little lighter/flimsy that others, but I figure, for $40, it can't hurt to experiment ! Plus, I like how the purchase opens up a bunch of new options on my kettle, even IF my Stok gasser dies an untimely death...the inserts will live on !
