I was at my local Walmart and they had a closeout on their turkey fryers. They were the 4 welded legs types, 21 inches high. Complete with burner, regulator, pot, basket and thermometer. It was marked down to $20 from $39.95. They also had a double burner for $30. I had the double burner in my basket, but I really didn't need another one, so I put it back.
If you need one, check out your local Walmart to see if they are on close-out.
