Its poss one of those things you debate buying and then when you get it you wonder why u didnt buy one sooner and how u managed without it
Other thing is the software side and how difficult is it to sort the image to print it
Nice example of them was the last series of Car SOS, my memory dont get better so cant remember the car but they needed a centre cap for one wheel, so he took it to guys who scanned in original, reworked image and then printed new one, but it takes longer than you think and thats if you know the software.
Think they had 3 so just had one printed but i would of done 4 and you could see 3 originals to pay for it, once the image sorted obviously then u can do print endless supply, so you could then make printer pay for it self
Brilliant though but sorry i know nothing about them myself. Apart from the price is higher the bigger the items it can print
