I always trade up my tool collection. Had a Makita worm drive for years, but bought a locker with a like new Bosch worm drive....kept the Bosch and sold the Makita.
Bought a locker that belonged to a guy that had a lot of nice cooking stuff. There was a beautiful set of eight JA Henkels steak knives in a nice wood box......I use those any time I have a hunk of meat!
Got a nice Kitchenaid mixer with bunch of accessories a few years ago, and with the holidays coming, it will be getting a workout soon!
Also found a very nice Cuisanart food processor (a nice heavy duty one, not the junk ones I usually find) with all kinds of accessories, and it still get's used frequently.
I have traded up my dining room table a couple of times and have a really nice set now. My entire bedroom set (the nicest furniture I've ever had in my life!) came out of a locker.....a complete set of Drexel Heritage, Queen bed frame and dressers. Very nice stuff!
I'm always grabbing paintings I like......pretty much only original oils and I have to like the picture. I have them hanging all over the house. At this point, when I find a new one I like, I have to sell off an old one.
There's more, I find decent clothes from time to time, and of course lot's of little hand tools, wrenches, specialty tools, tool boxes, etc. And then the stuff you need all the time.....cleaning supplies, paper towels, garbage bags, etc.
But, having said that, at this point in my life, I have pretty much everything I need and after years of digging through other peoples stuff (the name of my business by the way....Other Peoples Stuff....LOL), I don't WANT anything anymore......it's just a bunch of things! I refuse to pay storage on personal items....I will never pay for personal storage again. If something strange were to happen and I was booted out of my house tomorrow, I would sell everything on CL or ebay before I paid to put it in storage. I have seen over and over again, all these people put $500 worth of items in a storage locker, and then pay thousands and thousands of dollars in fees to store it for years! And by then of course, it's dirty and outdated, and it probably wasn't that nice to begin with!
