I downsized my office machine to a GS3 AV. I am sad to have to part with this. Completely rebuilt 2 group linea that was used for 1.5 years in our office pulling no more than 15 shots a day. This was a hobby project for me to rebuild with our local la marzocco service company. I have pictures of the original version which was UGLY. Only part that was not replaced was the main boiler which was acid cleaned and restored to like new condition. Comes with the pump. Only purified RO water ever entered this machine.
