I've searched all over the net for advice on BBQ Guru's Onyx Oven smoker, but haven't really found a whole lot of information on them. The only info I could gather about the Onyx is that they are built a lot better than they used to be and that they hardly use any charcoal. What caught my eye though are the wide cooking grates that can easily fit untrimmed briskets and spares as well as full pans. With that said, does anyone here actually own one of these cookers?
