Piasters (€) are the hardest resource in the game to get and to save up. Any time you can do something to save spending them is worthwhile. Also, the Nano Generator is one of the best buildings in the game; most people would spend all the € they have to buy as many of those as possible. If you want the Nanos I would definitely advise using your Elite economy scroll.

If you have other economy scrolls (preferably the Large ones) you can use those on the second and third Nano purchase to save €10 per Nano.
