Vasco,
You need to do more work on researching the Super X3 before buying as there are problems with it.
Two have been imported locally to me in the UK and I have had a chance to run one for a short while and was not impressed.
The problem is with the new motor drive. The specs say something like 1000w when at max speed the controller board only puts out 500w.
Top speed is stated at I think 1800 rpm [ don't have specs in front of me ] but actual revs were around 1500 which is far too slow for a machine this size.

Under load with a 5/8" end mill you can quite easily stall the spindle and when you select the tapping option it's possible to stall this by hand on the chuck.
Both machines have had problems due to the fact that the mains tracks on the circuit board are that close to the mounting standoffs that they have both blown a section out.
The importers have stated that they will not be importing anymore, this doesn't maen to say other won't.
The second machine which went to a company for evaluation for CNC conversion and there development guy is unsure what he is doing with his, he said he might just sell it on to get some costs back.

This only applies to the super X3 and not the standard X3.
