But on a tangent, it is common to see comments here and elsewhere about how you don't need much possessions, hoarding, Kondo Marie, etc... But tools and supplies like screws, gaskets, electrical connectors, spare parts, etc... take a lot of space, and you will need them at some point. You don't know which one and when, but you will need it.
Here the author already had a bunch of tools, and yet was missing a hole saw, a good drill, a large spanner, longer hoses, and a spade drill bit. He bought 3/5, but I guess he will keep them, it solved a real problem and he may need them for later, in case he moves again and have a similar problem, and maybe not with an available hardware store close by next time. And cumulatively, these things are not cheap, and hard to sell without a steep discount. Personally I would have bought the good drill BTW, it is expensive, but it is one of the most used tool, and it is a bit stupid to have a hole saw but no drill to fit it in.
In the end, you find yourself needing to go to the hardware store less and less, but you end up with a workshop full of stuff. The alternatives are to pay tradesmen, which will cost you, and you may not have one available right now. Or, which in my experience is the most common, invite the friend with the tools to dinner ;)
