This little LAP meter from Screwfix:
https://www.screwfix.com/p/lap-dc-digital-multimeter-600v/793rt#product_additional_details_container
Is a good budget choice. More functions than the <£5 one and readilly available. It is also safer (CATII) than the cheap ones for mains use.
A good used choice recently were ex-MOD Fluke 25s These can be had for as little as £30 on ebay if you can wait for one to turn up at the right price (couple at around £50 at the moment).

Far too many multimeters here including 15 Flukes up to 6.5 digits….
