These are the updated versions of the classic DF64, with some significant improvements offering single dose capability out of the box as well as timed-dose grinding via a hopper on the DF64E. I've been using the DF64E purchased from them for about 3 months and have enjoyed it (upgraded from Breville SGP)
These are a limited time deal shipped from Asia. I think the stated RRP on the website is a bit overblown but for comparison Espresso outlet sells the DF64E for $448 and doesn't ship to Australia. Only place to get them locally seem to be $1149 each from Coffeeparts and currently out of stock, so a significant discount from retail.
These are a bit more expensive than the Eureka Mignon Specialita grey market from ECS in Europe, but offer a few improvements in terms of single dosing as well as aftermarket burr compatibility. Note that they are espresso only grinders unless you want to open them up and set them manually. Probably similar caveats apply with regards to after sales service and warranty whilst buying internationally.
Wow surprised SSP burrs cost so much as an extra. Is that standard pricing?
