Hi everyone, I received a Smokintex 1400 from my cousin. It's well used but it works great - already smoked some cashews, and a pork loin. I've been inspired to start producing more cashews for family & friends but I have a problem... I only got one grate with it. I know I can just call the company and pay $30 +S&H each, for two more, but does anyone know where I could find a cheaper set? The racks are 14 1/2" square. Thanks!
