I think price really depends on the puppet type, size, materials used, ect.....Media rights? So, there are lot's of factors that can influence the price of a puppet. Is it the only one? Or is there more than one. Also, it just depends on you are willing to pay for the product. Vent puppets for instance can vary greatly depending on materials used, mechanism design and over appeal of the design. Also the very last thing is...... your need.
