Gday "oneaday"... :)
Of the domestic grinders made by Gaggia, the MM isnt a wonderful performer to be honest. The next one up though, the MDF, is a great little grinder with many long-term happy owners. See how you go when it arrives (probably give it a really good clean-up beforehand though) but I think you will be a bit disappointed in it after a while.
All the best,
