How much would you pay for a prop flail?

I am making several prop flails that don’t look too bad. I am wanting to sell them on EBay. They have a wooden handle steel chain and for safety purposes a rubber spiked black ball. How much would you pay for this? I have seen some on eBay that look awful that are being sold for $30

Nothing! This is "boats & boating" not "weird & weirder". Who would want such a thing anyway – Most Medievil Knights these days have traded their weapons and armor in for Abercrombie & Fitch and iPods & iPhones.
