I find it somewhat cute that according to this article, $500 is "grows on trees" kind of money. In the espresso hobby, $500 is barely enough to get a decent grinder.
But yeah, definitely don't discount manual grinders. But note grinding for espresso with a handgrinder is... an exercise. lol.
Although I would like to discourage anyone from getting a Eureka (Silenzio). grind retention is insane on those, and the higher priced models are the same flawed grinder with more LCD screens.
