Bakerstone Grill Pizza Oven Box At Costco

On my most recent stop at Costco, the item that caught my attention the most was this Bakerstone grill pizza ovenbox.  On their site, they list it for $129.  What's most interesting to me is that this thing has a baking stone at the bottom - but ALSO at the top - of the box.

From the description:

The BakerStone Professional Series Pizza Oven Kit provides you with everything that you need to turn your grill into a restaurant quality pizza oven and transform your backyard into a gourmet pizzeria. With the BakerStone Professional Series Pizza Oven Box, you'll be able to bake gourmet pizzas in around 2 to 4 minutes, bake artisan quality breads, sear and roast steakhouse quality steaks, pork chops and fish, roast vegetables, and even bake bakery quality cookies and other delicious baked goods. 

The BakerStone Professional Series Oven is easy to use. Just place on the cooking grates of your grill and preheat like normal. The BakerStone Pizza Oven Box absorbs the heat produced by your grill and creates a baking chamber that utilizes convective, conductive and radiant heat to provide a superior baking environment. The easy to read Heat Indicator tells you if you are in the baking zone or the stone oven cooking zone.

They also list the dimension - which call for a 24" by 17" (rounding up!) interior measurements for this thing to fit 'inside' your grill.  You'll want to be be able to close the cover, so you should have a little bit of wiggle room.

This won't satisfy my strong urge to actually build my own pizza oven, but it *may* satisfy that craving near term.

Guess I gotta get my boots on and measure up to see if this sucker will fit...
