HI, I read alot about Tagex's La Marzoccos and most seem pretty good. They are all ex-Starbucks machines, and apparently Starbucks had a pretty strict maintenance program for them. They are selling them because they are changing the type of machine they use at thier stores.
Coulpe things to note:
Tagexs machine have no legs on them, you will need to buy some.
They have only 1 portafilter.
They were taken out of the stores quickly and so power cords are cut. There is water in the boilers still.
They may need descaling, and at the very least a flushing of the boiler.
They will all need new group gaskets, dipsersion screens.
But overall, assuming you spend an extra $1000 (which is about the max unless the machine has real big problems) you still got a good deal!
