Oh, don't get me wrong, I am committed to my old Kenmores, but I just bought a Windsor (brand new Sensor S12 for $256 on eBay, that is practically a curb find) on the strength of seeing them at work daily in my office and I have to say I am impressed with the precision of it's construction and the way it cleans. It looks like it will outlive me, which is more than I can say about the crappy old Hoover upright "U-Boat" it is replacing (though something weird in me pushes me to restore even this old pile of cheap plastic). The hose attachment is just horrible. The Hoover bills itself as cleaning 99 point something or the other allergens but I dunno .........
At any rate, old Kenmores own my affections. The eldest of my Kenmores has a big Ametek Lamb motor in it, and I kind of over did it. If it pulls suction hard it sucks the lid in pretty dramatically and it finally broke the hinge on the back of the lid. I don't think I can find a replacement for that part (maybe a piano hinge???) but I have a slightly later Kenmore canister that came with motors that powerful and it has a sick sounding motor, so I see a motor swap in the near future, heh, heh, heh.
