1: I can not comment on the Coffee Machines at this level.. Will leave that to others..
2: Having both the EM0480 and KG100 - I fail to see how the KG could be scored above the EM0480.
Get the best grinder you can afford and that way when you upgrade you coffee machine you grinder will still be of use... It will also give you more control over you coffee and options even with the cheaper machines.
Lots of chat in the grinder section on the EM0480 and how to clean and mod / adjust the grind if your system needs it.
NOTE: Fresh beans is a must....
