SmokinOkie provided an Amazon link to a backpack grill. I ordered it and this is what it looks like in the ash bin. Unfortunately, I only ever have time to smoke on the weekend, but I figured I would share what it looks like so far in case anyone is interested. The grate feels well built and seems sturdy in the bin. I have high hopes that using worldbfreebase's suggestion of putting some briquettes under this grate will let me consistently smoke some pieces in the bin.
