One last question - how would you recommend going about adding a 5th axis? I
could live with 4 axes for now manually setting a 5th axis (e.g. tilt - but 5
would be ideal).

Also, the Ultimaker has considerably higher resolution. If I were to buy a
standalone unit (and I am seriously tempted) I think I would go with the
Ultimaker (larger print volume too).
