I'm looking to get a coffee grinder. I only care about espresso, I don't think I'll want to use other brewing methods anytime soon.

I'm in Argentina so I don't have many options available unfortunately. Sorted by lower to higher price, these are the candidates:

- Fellow Opus
- Baratza Encore ESP
- DF64 II
- DF64 V
- DF83 V

I was leaning into the Fellow Opus initially, but then I saw many reviews pointing that is not really good for espresso, and it only makes sense if you care about other grind sizes (which I don't really).

Also, the prices can be distorted. The ESP is same price as the Opus. The two DF64's are 2x the price of the Opus. The DF83V is 3x the Opus' price.

Any opinions? Also, does it worth to consider a manual grinder instead of an electric one? 

Your expertise on this subject is truly impressive!   Chúa hề! @huyenmin
