This is the best capsule-based espresso system out there, and it delivers consistent results, considering its price. Even better, it won't steal much precious space on your counter. To operate it, you simply open the top and drop in one of 19 varieties. The output is a fine shot with crema (the froth that crowns great espresso). [$179; nespresso.com]
