I live 10 minutes from the owner. I order the rack, it's either in stock or he tells me it will be a week or two, then I pick them up at his house.
Again, call either Jeff or Lindy and ask if they have the frames, the heat panels and the tubs in stock.
Unlike some of the plastic rack builders FB and ARS often have all the tubs, panels and frames already made. I've been to their facility (FB) and have seen the inventory.
