Hi Filippo,
I have one, see this link :
http://eu.xyzprinting.com/eu_en/Product/da-Vinci-2.0A
I look, they sell it on Amazon.it, me i buyed on Amazon.de because it's not proposed in France.
I buyed since march 2015 and i have do a lot of things, like this (see photos) and of course more technical things also.
The duo is more than 600€ but the 1.0 without scanner is ok (it's totally not needed and as i know, not really good like scanner). I do all my parts in 3D with Sketchup or 123Design by Autocad they export directly in good format stl the both.
You can't have smoothen parts if you don't use acetone vapor to finish, of course outside !
As you see on the photo you haven't a good finish without acetone. But it's not so bad, that depends which machine you use and the parameters you put, more it's smoother more it's long to do.
As all time the things need a bit work by DIY to do.
If that can help you.
EDIT: And Filippo, as you said, don't believe that you have nothing to do before using a 3D printer.
At least you have to adjust your printing surface for it's totally straight in x and y axes. Believe me it's not a simple thing to do it, for example, to do lithophane (the most difficult thing i have do) you need at minimum of 3/4 of hour to adjust, some time more, that depends how your printing surface is calibrated at begin
But this model is ok, at the delivery unless of controling the calibration of your printing surface you can start to do a model, only the driver and software to install
