I am going to be opening a small Espresso/Juice Bar on a shoestring. Of course i need an espresso machine. I have read in the posts that the Pasquini Livia 90 is a good machine to start. I really do not think this will be quite enough machine. What brand/model would be a step up from this with a very tight budget in mind. Thank you for the help. I would like a 2 group machine, but i would like to stay under 2K if possible, a used machine will be fine.
