I'm always keeping an eye on induction hobs as this is what I eventually plan to have in our new house. A really interesting (to me!) article is in the latest issue of Which?
They compared a best buy Samsung NZ63J977OEK at £799 with a New World IHF60T at £254. The Samsung got a score of 80% whilst the New World got 79%. Barely a gnat's whisker between the two for performance (Which? comment that the Samsung is slightly quicker) but a whopping price differential. The cheapest current supplier for the New World is Argos.
