Mahlkonig K30
Xeoleo ghost burr grinder from Taiwan. Buying Chinese knockoff grinders. Use for pour over and drip.

Recently purchased Bunn LPG for workplace. Easy timed grinding which all can use. Place funnel in and press one button to start.

Tried various grinders and shots from friends and resellers including Versalab M3, Sette, many Eureka models, Mazzer SJ, Bunn and Ditting retail grinders at local roasters. Hand grinders including Pharos (not for me) Seem to prefer flat burrs for espresso not only for taste but find I can grind directly into basket without the need for WDT (mixing / stirring grinds) common with conical burrs.

dozens of vintage Dienes / Kym / Zass hand grinders (still have most of them but they don't get used anymore, I just love the way they look)
OE Pharos 1.0 (sold)
OE Lido 2 (rarely sees use)

I really liked the results in the cup with both the Pharos and the MG-1, but I was just kinda over hand grinding.
