You seem like you know what you're talking about. I know pretty much nothing about freeze drying. 600$ to 1k$ actually seems reasonable enough for my personal production. Would I need anything else? My mental model of the process is...grind (I think it needs a different grind than pourover), put into the magic freezer machine, wait and have instant coffee to take to work :P
What's yield/power consumption etc. (for such a lower end consumer version). Anything else I should be aware of?
