I was just given this by a family member who was going to recycle it. I'm not expecting much with system, I mainly just wanted it to play around with as I've only had Windows machines so far. It doesn't have a charger with it. What would be my best option, buying an Apple charger or an 3rd party one? I'd rather not spend the money on an Apple one if a 3rd party will do, but I will if it's the best option.
