Ive been racking my mind about what grinder to buy for home use. Then i thought "duh, ask the good people on barista exchange". I only care about it is it grinding espresso well. I own a Rancilio Silvia espresso machine. I know theres probably going to be alot of people recomending the Rancilio Rocky. But im really trying not to spend that much, any suggestions will be much appritiated.
