Anybody have any experience with or opinions about the Marcuzzi Elegance One Group w/grinder (also seen it called Expobar). Am considering that for a coffee house versus a unit with a separate grinder.\r\n\r\nFrom what I've been reading, the grinder makes a big difference but I've not read anything about using an integrated grinder versus a separate one. I would suppose that it depends on the quality of the integrated grinder, and I've not found any comments about the unit I have in mind.\r\n\r\nAny comments would be appreciated.
