New powercord for MacBook I am considering going on eBay to try and buy a new powercord for my MacBook. I know that phones often advise that you only use the official charger, so I was wondering if the same warning applied for laptops and if so, I serious I should take the warning.
Apple owns a patent on the magsafe connector and hasn't licensed anyone else to make one, I'd be very wary of buying a third party one if you find one at all.

However, best I can tell a magsafe charger from any macbook seems to work with any other one, but if you get one with less wattage than your original it will charge slower.
