Which laptop can i buy? - 1

I would like to buy a laptop to work (surf the Internet, research…) I'm willing to spend up to 400 euro. If someone could please post a link in the comments from a laptop that is good value for money it would be very nice. I thank you in advance.

Go for buying and selling. Look for refurbished. 😊😷🌵

Which screen diagonal should it be? 12 "? 14"? 15.6 "? Even bigger?

The screen size is not important to me, it is about the function.
