Hi n0oxy:
Yes, my favorite brand is Electrolux. Also I've had 2. I should explaine. In 1993 I had my first central vac istalled, it was the second of the series, and I loved it. However, I sold the house in 95, and moved cross country, I bought the same one for the new house and it served me well for many years. My idea is stay with what I trust.
Now, as to my housemate, he'll want the basics, a no frills machine, and since I'm the one using it, I want my favorite brand.
Keep in mind however, for him it's only the thinking stage, and I've been asked to do the research. So right now I'm turning to the experts in modern vacuum cleaners. Personally I'm just as happy with my Electrolux model LX, and Kirby Classic III.
