Sterilising bottles

Moms, any advice on the best sterilizer to get? The microwave ones are supposed to be great but then someone else was saying you can just use cold water and add steriliser fluid to it? We used a steam steriliser before but it broke after a few weeks! Any tips appreciated.

Would definitely recommend the bucket - you can get specific jug style ones for bottles, so much less faff than the plug in/microwave sterilizers.
