A snake is worth what someone is willing to pay for it! Blizzards are not that common, and the main reason the value has dropped so much on them is because people are desparately trying to sell, so sell for silly money. I sold my serpenco female for 150, and she was worth it all day long. If you have specific plans for breeding, then you will make your money back, so its not so much of an issue. It depends how much you are willing to spend, and the quality of the snake.
