It's that estimated value that I was getting at. If you were to buy the KOP off the shelf, it's worth a lot of money. Are parts donated? Sure. This keeps cost down. But some parts need to be bought (or are bought at a discounted price), and for 1800 kits, that's a lot of money even for one or two items.
