I'm itching for a new phone and at this point it's still going to be the new iPhone or an SIII, can't wait to see what Apple comes out with (even if I don't get one).
Here is an very interesting article describing the teardown of an iPhone charger, showing that it is a particularly high quality device, and also a particularly high profit margin device. I had no idea that chargers were so complex.
Here is a similar article concerning a $2.79 no-name charger. Conclusion: dangerous; don't buy:
I don't think that the lesson is exactly that you get what you pay for; there are probably intermediate priced 3d party chargers from well-known companies like Belkin that are probably at least safe. But at least for electrical components, it's probably best not to go for the cheapest item sold on Ebay.
