They are not very cheap!
But it depends of what are you looking for! Do you want a decorative ones, or you want them useable? The prices are very variable and you should have in mind that the expensive is not always of high quality!
So, my advise is to look a little bit more in the Web!
The Swordforum International is very useful thing!
As for the prices you can take a look in the sites of Lutel, Del Tin.
You can search also with key-words "swords", "swordfight"...
"Swords" because most of the firms are producing not only cold weapons, but also armour and things like those!
