Soooo. Here I am with a three-months-out-of-warranty Macbook, and my adapter's just gone brick. The connection between the cord and the Magsafe connector has pulled apart, and the wires look all frayed to hell. It shorted out, blew smoke, and died--it doesn't seem to work any more, and I'd be afraid of burning my house down even if it did. I really don't want to churn out the disgusting $80 for a new adapter, or even the $40-50 for one on ebay. Can I repair it somehow? Is there any third party adapter I can use, or frankly any cheap alternative?
