Clay Pipes

I saw some youtube videos of people smoking clay pipes, and I proceeded to watch a video of some old euro-guy making them. So now I want one.

I've read that they're cheap, but the problem is that I can't seem to find them anywhere. I don't have any local B&Ms, so I would have to buy online.

If anyone has bought a clay pipe online, I'd be really interested in some pointers.

Thanks.
