I'm looking to buy a laptop for things like browsing the internet, admin stuff like sorting out important documents, a little bit of software development, and other things that aren't easy to do on a phone.

I don't think I need a particularly powerful laptop for these things, so was hoping to get a cheap refurbished one. Can anyone recommend a reputable place to buy a refurbished laptop for a reasonable price? I'm hoping to spend around £200, but not sure if that's reasonable for what I'm looking for
