Since so many people find swords "cool," you are very likely to overpay no matter what. If you just want to find a replica of a historical sword, they are relatively easy to find. The sword you will be buying will almost certainly be unusable as a weapon, but you probably aren't (or shouldn't) be buying a functional weapon in the first place. If you are looking for a "real" historical weapon, be prepared to pay a lot, for something that may very well look shabby rather than "cool." Most swords were tools, not works of art. An attractive, functional, and historical sword will set you back far more than you had probably thought of paying. Another route would be to purchase a modern "weapon" grade replica of a historical weapon, which will also cost hundreds.
