Ebay is cheap but often fake. If you're willing to spend money, go with a reputable seller. You might have to spend $250 or $275 for something that'd go for $200 on ebay, but you're 100% guaranteed to get an authentic piece. Like for me, I bought my Tulwar for $80 which is a steal. But before that I bought a totally fake Tulwar for $100 that's worthless. So you could say I spent $180 on my "real" tulwar, which is still like the world's worst tulwar. If you buy from auctions you have to factor in the money you waste on fakes. Assuming it's okay to plug antique blade sellers here, I recommend fagan arms if you want to be 100% confident of an authentic weapon.
