VERY interesting idea. I think you have nailed the price point perfectly, assuming the quality of materials is up to snuff.
I gotta say, BPS is my go to resource for my BBQ needs. I continue being impressed. This reminds me I need to stock up on a few things....
EDIT: ok.... price point looks a tad high to me when I see what is included. Doesn't change my original assertions": BPS is awesome.
