if you are from the EU i can recommend Tuxedo Computers. they have a wide range of laptops to fit your budget, and among those a lot of customisation options.
the only downside about mine ive noticed, would be that the keyboard legends seem to wear a bit faster than normal. then again that is because they are laser etched, which means for a small upcharge they will put whatever you want on there.
or Framework as others have mentioned, not only because they seem to have produced a great product, but also because their mission is definitely worth supporting.
