Affordable modern pivot doors

I'm a big fan of pivot doors, but for some reason it seems like it's really hard to find an affordable pre hung pivot door. At least in the US. If I lived in Australia, I could pick the one shown above for $2,200. It's made by a company called The Door Keeper, and they have all sorts of options in standard and pivot doors. Something tells me the shipping wouldn't be cheap.

Anyone know where to buy a prehung pivot door stateside?
