Hehe, yes, I am sure.

Mine was 800€. To pay this, you need to be a coffee nerd, but I think it is absolutely the most important thing to get consistency and satisfaction. I use an inherited antique ceramique (no plastique) pour over filter and do not feel it has any drawbacks.

I will try Tetsu's technique.

Hand grinders are quite nice return of investment, for the same quality of grind you can pay a lot less, because there is no engine etc. Also hand grinders have much less of a problem with retention.

Grind retention is : /

I use a Rancilio MD 80 that I picked up for 80CHF. The guy I bought it from didn't know what he had. It's as large as my Gaggia, but grind retention be damned, I'm not giving it up.

What is retention?

To further explain, residual coffee goes stale, the oil in the coffee beans can go rancid and thus spoil your cup and if the retention varies you might miss your ratio or go overboard.

This is in practice at most annoying, so you can indeed make good coffee without a zero retention grinder but for a 'coffee snob' the most important thing is consistency in the cup.

Retention is residual grinds that remain in the grinder between uses.
