I use as my home machine and can also supply the S1. There are two models in the Veneziano range: The A1 has the volumetric touchpad and the S1 has the lever operated e-61 group as per the Giotto. Both units now ship with Giotto premium metal insert handles/knobs and have an inbuilt rotary pump as well as cool touch wands. Boiler is 2.5 litre and the tank is 2.9 litre. You can swith between tank and plumber with the press of a button...
As for your sales rep....I regret that he was wron, wrong, wrong! ;)
They are a superb machine!
