I really wanted a top tier. Instead, I did a seville classics wireless shelf unit, 18" shelves. Cost about $80, works awesome. I use all gravity, including directly into the fermenter. Use a cutting board or cut down a tile to make the shelves nice and flat.
Going to spend my money on more great burners / kettles.
