SmokerKing - Well done!!
Possibly change your handle to UDSSMokerKing - because, as stated earlier by PMAD, you are an artist.
I really like your diffuser, and I've seen it multiple times before. I wouldn't mind ordering one, but can't seem to get the website? Could you help me out with that? Have you tried the pizza pan method with holes drilled in it? I like how yours would gradually let the heat escape.
