Hario Switch for me. The cheap manual devices make the best brew. Mind you, I make only one strong cup in the am and it's just for me.
The V60 and the Switch are so good! I prefer the V60 when I have time to brew, but the Switch also makes a great cup that's a bit smoother tasting (which is good sometimes, not as good other times), and requires less supervision to brew.
V60 is still the undisputed champ for cleanup though. Dump the filter in the trash, rinse the dripper, and you're done.
