I recently bought an Amazon FIre Tablet for 35 bucks to use as a status monitor for the printer. A little decadent if you realise that it's a full blown tablet, abused for the sole purpose of being a screen. Yes, it's cable-tied to the frame! 

Nevertheless it looks a little more professional now.

Btw. tried out new resin made by Valent Resin from Lithuania. Check it out here:
