hand cranked ceramic conical burr coffee grinder?
As much as your question in its current form might be off-topic, I like this grinder so much as to answer the question anyway. :) Hopefully not too much shame on me...?

Hario is a brand with many good manual and ceramic burr grinders. I like this one. You say effort is okay, but it will take a lot of effort to get beans down to Turkish-level powder. 

That said, a web-search for "manual ceramic burr coffee grinder" returns many results. We're you not happy with those, or wanted reviews? For my cost-benefit equation, I'd buy the tin of pre-ground.
