Range extenders

I’m looking to buy a range extender for my WiFi. I currently have the 1K Virgin media package (UK) and would like to make the most of it. I’m planning to have at least 1 Ethernet connection.

There is a so many options and I’m not sure what to go for. My budget is £100. Any recommendations or any information to look out for? I am aware some extenders limit cable speed and 2.4Ghz speeds
