I have this cheapie immersion blender and it's served me well for years. I almost exclusively use it for soups. I don't love a totally smooth soup and this suits my tastes perfectly as it's not so powerful that I'm left with baby-food soup lol. I like a "thicker than broth" base with some chunkiness.

For the soup I make with cauliflower/curry I usually add Greek yogurt to my bowl before serving to creamy it up and serve as my serving of protein. It's so good!
