Pretty neat. Definitely recycles a lot of electronics in a good way. On the GPIO pins I would definitely replace the connector! I can tell you from experience that even if the pins straighten out, some random plugging/unplugging later and the pin will break off and the next person will end up replacing the connector. This is much easier if you have a setup already for doing the work. This is also a really great way to "pay yourself" to learn to do rework. Buying 200 at £61 and selling the fully restored ones (which appears to > 100) at £9 is at least £900 revenue from the experience. Granted, since you are "learning" that would be slow work at first, but later it would become fairly routine. So something someone in high school could easily do.
