Vinyl gutter downspout cut to length and put in a milk crate or plastic tote for cheap storage or use central vacuum pvc pipe which is smaller and reduces hook tangles if you prefer. I don't have the smaller cast masters so I can't help there. Posted from my iPhone/Mobile device
I looked up central vacuum pipe and that stuff is extremely expensive! Are there any cheaper small diameter tubes like that?

DZ beat me to it - milk crate and tennis ball containers. Fortunately, my wife plays tennis, and balls are discarded after use. Check out any nearby racquet club.
