For your needs, you likely could buy any laptop out there and have it do what you want. Laptops are pretty cheap these days and most of them would do what you need. If you aren’t planning on storing large files, like movies and stuff, on the machine, then you won’t need a huge hard drive for the kind of apps you are talking about. The only thing I would recommend is to try out the laptop and see if you like the screen display and the keyboard, some laptops have crappy keyboards and or displays. One thing I would recommend (if you can find one in your price range) is that it have an SSD drive (solid state drive) rather than a hard drive, they usually are more expensive but the prices have come down, and they are wonderful, they allow the machine to boot a lot faster and they don’t fail the way hard drives do. The other thing I recommend is get it with 8 meg of memory if you can, especially if you get one with windows 10, more memory will make it work better and these days that likewise is not expensive.
@ccdd14 has a good idea, if you can find a used (or even new old stock) laptop that is the same as your current one, they can swap the current hard drive into it and you won’t have to go through installing software on the new machine and backing up files from the old drive to the new one.
