I am struggling here... I don't understand this "too much - too many" idea... whatever the passion, space and bank balance will permit! But on a more serious note one of each and every variation of Electrolux USA and Canada production from birth through the last of the metal bodied machines and then of course one must have one of every Kirby, Rainbow, Hoover of a similar breadth to Elux, FQ, Lewyt, Westinghouse... oh hell... I want them all!!! they are all so similar yet so very different and the beauty of design, especially those of the 20's til 40's, but really anything until the 70's is just stunning.
