Dan, Did you purchase the new Guardian Ultra? There was a thread on here a while ago but I cant remember if you said you bought one or not. I'd like to try the new Guardian even thought I really do love the Renaissance body style machines.
That Guardian Upright looks like a fabulous machine and its one that I'd love to have in my collection sometime in the near future. My love of Electrolux Uprights started with my neighbors Discovery II and it was love at first sight! lol I've had several Lux uprights over the years but the newest model has apparently fixed all the flaws of the previous machines, which I imagine must make it one awesome upright vacuum. My next door neighbor, who has been one of my mothers closest friends for nearly my entire life, purchased her Discovery in 1987 or 1988, and even after 20+ years of using the same body style it really is a wonderfully designed, easy to use, and understated upright. The Discovery II was also the first Electrolux Upright that I purchased for my own collection and I regret selling it along with my Epic 3500.
