Under $100 - Ifixit's pro tech toolkit ($75)
Used it to assemble and repair my desktop computer, swap laptop SSDs, deep clean my mouse after my cat puked on it, and completely disassemble and reassemble an entire printer for a school project. It has easily paid for itself several times over, and is still in near perfect condition after 4 years of use. Invaluable for any computer, electronic, or right to repair hobbyists.
Barely Under $1000 - a Sebo E3 Premium canister vacuum ($950 after using resellers 10% off offer)
Our family's traditional standup vacuum (I forgot which brand but they're almost all identical) died after a few years of use and we were fed up with having to replace it. Most consumer vacuums available in the US suffer significantly from planned obsolescence, so I did some research and came across this German import Sebo e3 canister vacuum. Previously I had never heard of canister vacuums, they're literally never advertised in the US. Apparently Shark makes a few, but I had to specifically google "shark canister vacuum" to find them as there is no mention of them on their official website. It only took a couple raving reviews of canister vacuums to convince me of their potential, so I took the plunge with the Sebo.
I can safely say that this vacuum is a complete gamechanger. It is so much quieter, lighter, maneuverable, easy to use, and cleaner. No longer do floating dust particles cloud the windows' sun rays. No longer does my cat appear covered in dust because she found a spot I neglected to clean. No longer do I have to worry about breaking a weakening but crucial plastic clip or retainer when emptying the vacuum. Every part that experiences stress is metal and designed for longevity rather than aesthetics. Dare I say I even enjoy vacuuming now! It used to be a pain to lug around an entire upright vacuum over every square inch of the floor. Even the bags are better than emptying a canister. The bags are biodegradable and seal inside the vacuum, meaning dust never has a chance to escape. I used to have to empty the canister vacuum outside because of how much dust it released. Yes, the high price tag is rather intimidating for a vacuum purchase, but it's well worthwhile as it's been going for four years strong with absolutely zero issues. Also, most US resellers offer 10% off if you just call them to order it.
