The kettle is probably the least difficult item to get. You can find one pretty much anywhere. You need something that will heat the water quickly without making the handle too hot, so look for one with a rubber coated handle. A kettle with a whistle that doesn’t bug you too much is nice, but it’s hard to tell before you buy it. I like Bed Bath and Beyond because I almost always have a 20% off coupon laying around my house somewhere. You can also get your tea strainers here, but they wont be as nice as if you get them from a fancy place.
