When I was looking a while ago and nothing from the main manufacturers was in stock IKEA induction hobs were reasonably well reviewed by Which - think they got a best buy. I eventually went for neff to match other appliances but still awaiting delivery 2 months later. Maybe worth a look?
Need an Induction Hob but budget is max £500 - best to go for lower end Neff/Bosch or midrange Zanussi/Hotpoint with more bells and/or whistles?
