1 pointI have a Z400, no longer in use. Not a bad machine but they are getting old, about 2 generations out of date and Fastcorp no longer has parts or offers support for them. Never had a glassfront frozen machine so can't really compare. I like the chest freezer design for ice cream/ frozen foods, you do need to defrost the unit from time to time to keep things working properly. I would look for a newer generation fastcorp like the Evolution if you were going that direction.
