just remember to get a chamber you can add a little heat too. naglene dessicators def aren't the answer.
I THINK I'm leaning towards a provac BUT saw this one I can't find again to save my life.
It was one that came with griddle and chamber you just pop a 13by9 pyrex baking dish in and go.
Its made for the dish. If anyone has info please feel free to pm me a link.
