i am in the market for the following items, i know where to get them retail, but i was hoping to save a few $. i am looking for 1. a hydrokor digital thermostat. 2. hydrokor or exoterra heat cable. 3. an all american pressure cooker/canner of at least 21qts (model 921or925) or an all american autoclave/steroclave. (models 1921 or 1925x) i know, its a long shot, but its worth a try. thanks for looking.
