I would suggest getting one with a thermometer in the lid. The one I purchased has 195-205 marked in red so it's easy to see when it's ready.This is the one I have and it works great.
If you are fresh in coffee, but a gooseneck kettle will help you control the water flow easier, a built-in thermometer will also help read the perfect temp for brewing. Whistled Gooseneck kettle will let you won't forget the kettle is boiling water all the time.
