Around £15 from ebay.

This is the one I have (though I got mine a bit cheaper)

There are some that are cheaper, but this one does take account of the
power factor which makes it more accurate, some chepaer one smay not.
They often don't say.

Or this one from Maplin at £12.99

Which is exactly the same as the one in the link I gave, though cheaper
though when I got mine Maplins were selling them for about £30.
