I wonder where Lego gets the tubing from. I doubt they make it themselves. I bet there is some supplier that will sell you 100' roll of it for $10. I have seen many close equivalents, but has anyone found a really good match that is easy to order (...) (25 years ago, 9-Nov-00, to lugnet.org.ca.nalug, lugnet.org.au, lugnet.technic)
