I bought mine from DID Electrical in Crumlin, but it's a few years back and I didn't shop around that much, just compared one or two prices. I bought a Nef because I like the brand ... wasn't cheap, about 4 times the price of a gas hob. No idea how much they might have come down since.
So, sorry I can't help you on price, but I can tell you I would never cook on anything other than induction ever again.
