Nice machine. I recently acquired a newer 2009 model WindTunnel Anniversary U5491-900 model for a little over $20 at my local DAV store. Only issue with mine is that it needed a good cleaning mainly. Had all of the attachments, no broken parts and even came with 3 arm & hammer bags (one used one that was already installed; two more that were still new and unused in the package which was attached to the handle) That and a new belt (it had one but it was worn out and was dry rotting) and it works perfect! I have a video on the original acquisition on my channel, and will post an update on the next several days when I complete it since I've been so busy with the holidays. I also have a 1997 WT Supreme which is in pretty rough condition, I got it from an elderly family member who was the OG owner. She moved to a new house with no carpet, so she didn't need it. It works, but it needs a new cord, bag door (it's like the machine in this video, except BOTH clips are broken so it falls off if you tilt it forward), new extension wand holder (one of those clips are broken so the wands fall off during use) and a new hose holder (again, same story. I have it taped to the machine so it doesn't move but it still triggers my OCD lol)
