Watch Cabela's. They sell a Kajun Cooker or Bayou Burner or some such Louisiana themed turkey fryer for real cheap sometimes. I got one. Well Under $100. Maybe under $50. It was cheap. You get a stand, burner, regulator with hose, fittings and a safety timer, aluminum pot with lid, lift out basket (or did I have that already?), grappling hook (turkey rack) and coat hanger (turkey rack lifter). Maybe even a thermometer. No tank. You gotta buy your own tank. They cost about $50 for the first one and around $20 for exchanges.
I've used it for two tanks worth of propane and it does fine. It aint fancy but it gets the job done. Works every time.
