I was going to write a bunch of things about the Switch but I guess they would apply to most other pourover drippers too. I’m coming from the Chemex as a comparison, which is lovely but a bit slow and unwieldy for that one cup of coffee.
Having said that what makes the Switch stand out to me is that it feels like such a high quality piece of kit, and having the immersion element in the mix really suits me. My brain interprets that as “big aeropress” for whatever reason.
I know you don’t want to spend too much but there’s also no point buying something that misses the mark in terms of the grind you need for the espresso you want. When I was looking at grinders for espresso I narrowed it down to the 1zspresso J-Max for a hand grinder or the Baratza Encore ESP for a machine grinder. Both are a bit more expensive than the basic options but give much more versatility for dialing in grinds.
