I tend to buy the best that I can justify rather than the best that I can afford.
I would favour buying middle priced tools initially. They will be fit for purpose and will allow you to do what you need them to do, perhaps not as well as top of the range but much better than the cheap stuff. You can also use them and decide if a given tool or brand adds value to your work or interests. If it doesn’t, you can often sell it on and buy something else.
Unless we do things professionally, where time is money and quality differentiates you from your competition, there is seldom a need to buy the absolute best unless the budget can justify it.
So, while you could go out and buy yourself a few Festool power tools (which I do rate highly), you could also drive to the local DIY store and buy a load of cheap brand stuff which may be fine for the intended job or may be unfit for purpose very quickly.
Equally, you could buy some professional quality stuff, mid priced, from companies such as DeWalt, Makita, the Axminster brands and so on and get decent value and longevity. Your budget may stretch to a wider range of tools and this will make projects easier as you wont need to improvise as much.
Also, don’t overlook used tools. Chosen carefully, you can get some really good stuff for quite reasonable money and if it packs up after a while, you will have had use from it and learned how to use it and possibly not over paid for it.
