I am an authorized dealer for 12 different manufacturers including most of the ones mentioned here so I can’t comment on which make is the best for your situation - but I can speak in general terms about how I advise which price point and which features are the most appropriate for a cafe owner in their specific market. AlanBruce makes a good point about cost/benefit analysis and you have about two years of costing to help inform the price decision. You have to balance the monthly take against your equipment costs and budget for the machine that way unless you see an increased earning potential for the new machine. You will want to run the numbers on Leasing versus a bank loan and what makes the most sense for you. Leasing opens up a number of benefits you can’t get with a bank loan, though borrowing costs tend to be higher. You also need to look at operating costs and what features like Gravimetrics can save you in terms of labour and product wastage. If the numbers don’t support it, don’t buy it. Finally you will need to work with your local technician so make sure he is an authorised dealer for the equipment you choose lest you run into warranty issues. If you can, buy from the local dealer, not online - you will get better local support this way and often it is the only way to get warranty coverage.
In the simplest terms, remember that it is a business machine whose ultimate purpose is to feed your family and you need to be sure the market you are in will support the cost of the machine in order to keep your business in the black. So be realistic about what you think the increased earning potential of a more expensive machine could actually be. Not knowing a thing about your books or the environment you are working in, it could even be that your numbers don’t support a new machine at all and your best option may be to refurbish the one you already have. Unless it is truly wrecked indeed (like both boilers punched) the FB70 platform hasn’t been in existence long enough for a proper refurbishment to exceed half the cost of what a new one would be. It would be worth at least sending it in to the shop for a full evaluation that way you know the repair costs or trade-in value against a new one.
