Is anyone familiar with LA PAVONI espresso machine?

I am planning to sell espresso coffees at my deli shop and I just bought a la pavoni espresso machine and grinder, it is used, bought it off ebay ad it looks good, it’s not installed yet, my question is if anyone out there who has had experience with this brand please let me know how well these performs and also is it easy enough for me to install it or qwould it be wiser to have someone else install it. It is 2 group espresso machine PUB 2, also is there a particular water softerner that works best for this or could I use just whatever is available. Any input would be greatly appreciated. Thanks
