ThinkGeek offers the Hammer of Legend: Mjölnir for $119.99. Plus, bag this Random Shirt of Surprising Awesomeness for free via coupon code "RANDOMTEE". (Add both items to cart before entering the coupon.) With free shipping, that's $42 under the best price we could find for just the hammer elsewhere.
