Unfortunately I have to agree with what others have said here about the 5th Gen. Read my review and head to head comparison with their earlier gen (and outstanding machine) the Rep 2 here:

We've been super-happy with our Lulzbot TAZs, adding to our fleet. They's slower than the Rep 2 but built like a tank. The 5th Gen is so slow, I think the TAZs might be faster. But the TAZs are super-reliable.
