I am going to share 2 controversial suggestions 😊
I have recently bought 2 (renewed) Thinkpads from this seller on Amazon - Rentopcdotcom — and both are going strong. Anything with an SSD should be fast enough and these Thinkpads are built well.

This is the x230 (I have the x250) but you can get some really good deals with renewed machines if you are ok with not buying a new box-packed laptop.
Otherwise, take a look at Chromebooks — I bought this one for my 7yo who is using it well. The touchscreen and converting it to a tablet works well and if you are doing basic internet stuff, it is fast and more than capable.

And both options are with 20K to spare 💰
