I remembered something about the person who sold me the tubes 5-6 yrs ago. The email address had something like Tarzan in it. Do any of you know anything about this? Also, FYI, I read in the archives that woodworking shops have some that are very sturdy though expensive. They are used to suck up dust. So far I haven't found them. Do any of you have them?
