Anything that isn't made by Apple.
More specifically, I've had good experiences with Lenovo (although their Z series/IdeaPad 500 series has plummeted in quality so I switched to another model) over the years. I've heard good things about Asus, although I've never used them. I'd suggest avoiding Dell if possible, as they tend to be somewhat poorly made and have lower lifespans (although their warranty was pretty good and they did basically give me a new laptop every other year while it was in effect, as soon as it wore out I had to buy a new one).
Also I'd strongly recommend getting a 1TB external HDD or something and keeping the bulk of your files on there - this allows you to save money on the main laptop by getting one with less space, and either way also prevents the inevitable slow down as you build up storage use on the laptop and also means if your laptop goes kaput you have your stuff still. If you do get a laptop with a good deal of space you can just use it as a backup, but I'd still suggest keeping non-essential files/things you don't go through on a daily basis, on the external, to avoid the slow down.
