That's cool, Scott.
I hope you get it. It would be neat to see and hear a demo of it!
I found a lot of Minuteman vacuum videos, but I didn't see any like that one.
As for the "As is" on the sticker; sometimes I think they just say that to basically mean that they're not responsible if it doesn't work properly, or if there are parts missing or something. It could very well work just fine. The stores in my area seem to put "As is" on most of the electrical things.
