Extra head only?

Question:  Just for future reference -- what would you estimate the cost to be for just a head for use with the same body as my figure?

From Mr. D:  Generally speaking, the cost of a head only is about 2/3 the cost of a complete figure.  Or, conversely, the cost of a body only about 1/3 the cost of a complete figure.  (Over the years I've actually sold more extra bodies than extra heads...extra bodies are used primarily for quick and easy change of clothes - one simply moves the head from body to body.)
