There is quite a market for broken Ipods, believe it or not. You can buy them in bulk broken, take them apart, and put together a working one or two to sell. You can even resell the broken parts for profit. Seriously. I bought a broken Ipod and resold it a week later and profited $4.00. That was a profit of 5%, and it was infinitely less risk and hassle than the monitor was.
That case was buy one sell one. However, if I was to buy a lot 4 or more at about $40/ea then the profit margin would be closer to 40-50%. My only real issue would be constant packaging and inventory in/out. Of course, time to try and fix one can be an added expense as well, if I wanted to bother.
