I totally agree with you, Karl. It's a deteriorating situation out there for impassioned collectors of anything who just wanna have a bit of fun. Look what's happened to the Lionel Train hobby in the past 15 years. With the explosion of internet access everyone 'knows what things are worth...and more! There's no fun to be had at Saturday garage sales when the guy wants $50 for a bashed up locomotive. And there's no point in haggling; you're speaking two different mindset languages. Just walk away and spare yourself the stress. When another one comes along reasonably priced you won't know about it...or, you'll be there, spot it and walk away a happy man or woman. That's how 95% of my Lionels & accessories were accummulated. For that special one of a kind item you'd sell your little finger. Fortunately, sellers prefer cash.
My Dad taught us kids "When you buy a new car, invest in the top model and get the bigger engine and take care of it". Dad knew a thing or two about future re-sale value; he was the Parts Manager at Stedelbauer Chevrolet/Cadillac in London. Of course this was back when a full size Chevrolet meant a choice of Biscayne, BelAire or an Impala. He'd quote the same homily any time something new was wanted. Mom would just sigh "Oh, Jack", let him have his way and of course basked in the aura of fine quality ownership. What does this have to do with old vacuums? Well, that Canadian Connie 841E that started this thread wouldn't have survived in such great shape unless someone took great care of it like my Mom & Dad & Grandparents would have. A simple hypothetical test - how much trash do you have on the backseat floor of your car right now? How long since it was last cleaned up? Are your trunk carpet & seat seams vacuumed regularly? Wipe the mud from your doorframes and sills after every carwash? Do you clear your rear window of snow & ice before heading out or just give it a quick swat with your hand? How much would your car be worth as a trade-in right now? It appalls me on a casual survey walk across the mall parking lot how people treat their brand new cars but heck, it's their car.
It makes me sad that I can no longer drop by the Salvation Army store and rummage through a big bin of hoses, wands and tools like I could 15 years ago, too. Stumbling across items like that Hoover polisher or Tom's astounding find is a genuine right place, right time thing, especially these days. Church rummage sales used to be a goldmine for domestic appliances. But I'll continue to go to these place because you just never know...
Would I be willing to pay $2000 for a new Filter Queen or a Kirby? No way. If they hadn't been out of stock at Home Hardware a couple months ago I would have sprung for the new Connie in stainless steel when it went on sale. Sure the new Connie ain't all festooned with today's bells & whistles but it sure is classicly purty. In the right hands it'll stay looking that good decades down the road.
