Perfect cup? Still aspiring ... Machine, grinder, a grand bean, & the all important barista work together in perfect symmetry, grasshopper! They're not separable mate. Seriously though, OW, and surely others party to this forum will maybe push their own similar findings from experience. I have my personal preferences on all levels (machine, grinder, tamper, milk), but it may not suit you. Bottom line, try a few of each before you get started from some eager suppliers wanting to sell their ware. Plenty out there, and don't get tied down to any 'contractual agreement' with any. Get a feel, get some training on each, then launch when you feel you're ready (ie confident enough that a customer will come back, with an accolade & not an expletive).
