Vacuum Cleaners Discussions

I just got suckered in to buying an Aerus Lux Guardian Ultra cannister vacuum. The guy told me it was the top of the line and normally sells for $1799. I had a very old (15+ years old) electrolux that I traded in and I ended up paying $1000 plus tax. Did I get a good deal? It seems like an awful lot of money for a vacuum but I was told I shouldn't have to buy another vacuum for about 20 years or so. If it matters, I am from Maryland. It seems so difficult to shop around because the dealers don't want to give you prices over the phone. My mother was the biggest influence. She loves her electrolux vacuums.
