Replying to Finding a Macbook Pro with busted HDD, best place?

So I'm looking to find a 15" unibody MBP for casual use around my house and on the go. Not going to be running video editing software, maybe a bit of PS + Lightroom, so I'd like to have a dedicated GPU. Processor speed doesn't matter that much, and ram can be easily upgraded by myself. Budget is $600-650

What I'm looking for is one with a fried hard drive, to get it for cheap and replace it with an SSD on my own. Anyone know of a good place to find one? I've looked on CL and ebay, but not a whole lot of luck (most "for parts" ones have water damage). I must be missing some place where someone is just giving one away because they don't know shit about PC's.
