FWIW, I own a Mazzer Mini and a sunbeamer EM0480. For a beginner in to espresso world, or for syphon/pourover/cupping duties, I think the 0480 is fine.
My biggest dislikes with it were too much play in the collar, leading to inconsistent grind sizes between sessions and the amount of grounds held in the throat. I routinely took it apart and found ~10 grams in there. With my MM, if I dose properly, I have less than 1 gram wastage.
