As someone who has worked on the volunteer end of the ln-4 prosthetic hand I find the author's criticism of it lacking. It implies the hand is fairly useless and flimsy, but I would check out this short video: http://www.youtube.com/watch?v=bpfeWpy0l2A to see otherwise. People can write, ride a bike and eat food quite successfully with the hand.

Looking at its financials (through 2010): http://www.ln-4.org/documents/89_Use%20of%20Funds%20v002.pdf the foundation has donated one hand for about every $80 total it receives. I would be quite surprised it is possible to do much better than that for this type of device.

Yes it may be somewhat difficult to take it on and off, but how often do you need to remove a prosthetic hand?
