Good condition iPhone 4 from ebay worth the purchase?

Used iPhone 4, has a minor scratch on screen, a few scratches on back, but also comes with apple care, for $280. Good deal? The other is a mint condition one with no scrathes, but is $300 and does not include apple care

That's a nice deal, but just buy a case like those Otter ones and/or a screen protector to prevent anymore scratches. Even carriers still sell the iPhone a few bucks extra

Get the $300 one, and an otterbox case.
