Where did you get that $60 from?
Gert designed the board so it doesn't need to be fully populated - you just buy the components you want. I guess to buy the PCB and fully populate it might cost $60 but I doubt it.
You will be able to buy the bare board. And I believe there will be options to buy kits of the bits you need, which will probably be cheaper than you can buy them individually.
