Hi BP, I have a 1 group Bosco, and am very happy with it. They are well made, and easy to service. Only electrical part is the element. A very good choice if you have to service the machine yourself. The portafilter is 58mm. There is an Australian agent, but you may be better off buying direct from Bosco. I would buy a 2 or 3 group unit for a business, not a single group. I agree with everything said above, but would like to add one element that everyone is missing. In today's cutthroat market, people do not want just a coffee, they want a story, romance and theatre if possible. Watching someone use a lever machine always draws interest, and is a good form of marketing for your business. Regardless of the food or beverage, the theatre of making, preparing or serving it is very important. People want to be entertained and educated, and are happy to pay a premium for this. Good operators realise this, and incorporate it into their offering. While new is always good, a well serviced second hand lever machine is excellent value. It will save you money. There is not a lot to go wrong with levers, so do check out what Fresh Coffee is offering. It just may be the perfect machine to get you started. good luck with your venture!
