I recently bought a Delonghi KG 100.
If that is the one you are looking at, I reckon it is pretty good for home use. Multiple grind settings, timer, clear hopper, simple square receptacle (the Gaggia grider I have has a weird shaped receptacle that gets very messy. One of the reasons I changed).
I started with a Breville (after the spice grinder stage) and found it could not grind fine enough. No such issues with the Gaggia or the Delonghi.
