I'd recommend the Kinu M47 too. It will likely be around 70-90 revolutions per dose IIRC, but it is very easy to crank and will last you forever. It will also be decent for travel (assuming not backpacking) and won't affect your learning process in any negative way.
It is a great grinder!
The Sette would do the job well (that's what I chose while awaiting the Flat), but it isn't a travel grinder like a hand one would be, so it will only be a backup once the Flat arrives (already have the M47s too).
LMWDP #581 .......... May your roasts, grinds, and pulls be the best!
