Like the rest of you, I think they're quite pricey. I really like the styling, but I have never smoked out of this kind of pipe and I'd be worried that I wouldn't like it. I really like the screw on cap idea, and having a screw on wind cap (when they go on sale by the end of the year). The modular design seems like it would be a breeze to clean. With all of the right angles, Im not sure how it'll feel in my hand.
But man, I like the way they look. Were they $200 or less, I might have been able to justify the purchase.
