I've owned this Expobar Brewtus IV for about 5 years. This is a dual boiler with vibration pump. I pull 1-4 shots on a semi regular basis. It has been well maintained and I have no issues with it. It has been upgraded with an IMS shower screen and I recently changed out the pressure valve.I have a case of upgrade-itis and want to sell this machine before buying a new one. I'm asking for $800 or best offer. I will include double and bottomless portafilter. I will send pics of whatever details you would like.
