That was my point, even the lowest quality rails of this design are going to be way ahead of any cheap, DIY construction that other builders turn to in order to save money. And I certainly hope supported round rails are better as well, that's what I'm using! Though If I'd seen these rails at that price when I built my machine I may well have chosen them instead.
