Get one which fits flush to the work surface - some people dont like the digital controls but I find them fine. Our hob has the ability to make the cooking 'zones' bigger which is quite handy when using different sized pans/trays
Would also suggest getting one that has a separate control for each ring. Fuck tapping away selecting, changing, deselecting rings on the panel when stuff is boiling over. We have a big 5 ring AEG which makes you feel like a pro without spending all the money.
@sohi @Jameo thank you.
In that case, any top tips for induction hobs and integrated ovens?
