If you go with the economy, it is really easy to paint them. I picked up 6 doz last fall and used a wide sharpie marker for painting the wings and a little detail on them. You'll need some pink for the heads. Or you could luck out like I did and open the boxes to find econo bodies and full color heads. BONUS! As to should they all have heads on them? It doesn't hurt to have them, but those that are heads up should be in the 1 to 10 ratio. The more heads up - the more alert and ready to fly they look.
