I havent used this breville but would recommend spending a few hundred on a grinder (iberital challenge, rocky, isomac all have grinders in this range but drop in and see a site sponser) If this means you have to wait a while for an espresso machine...so be it. With fresh beans and a decent grinder your drip and mocha pot will improve out of sight. It also doesnt pay to have a decent espresso machine and without a decent grinder. Youll hear the same from others at cs.
All the best and enjoy every step up,
