Have you seen the Aldi power meter?
It actually seems quite sophisticated,
certainly more so than the Maplin meter (which I have also used).
Eg the manual is difficult to follow ...

I saw the one that someone linked to a little while back (can't follow
the link now since they seem to have removed the special offer) - that
one looked fairly basic and did not mention an ability to measure the
power factor. Yours may be better - or the advert may have left out a
bunch of features.
