Thanks, Nicholas. Funny, I was the same with other brands, especially Hoovers, before I began meeting other collectors. I really never paid much mind to Hoovers because I saw so relatively few of them when I was a kid. I can only remember a couple of them and they, for whatever reason, didn't really make much of an impression on me.
Now, I have quite a few of them -- 12 or 15 I think -- and like the different eras for different reasons. I like my 102 because it's so primitive looking -- looks more like some sort of farm tool! Then the later 'motor dome' series are all lovely, especially the 925 that I still miss. The 150 is my favorite of all Hoovers. It just doesn't get any better than that, on every count - design, appearance, color scheme, lightness of weight, performance -- it's a great vacuum cleaner. Then I like the 63 because of the blue and gray color scheme. Then of course the space-age Constellation.
I am not really too wild about the later machines. I appreciate their beauty and performance but generally they're just later than my area of interest. The one that I'd love to have, just for the color, is the turquoise Convertible - the one with the headlight.
