Yeah, but it sounds like you're selling it based on different reasons. There are a few people here and there that are selling it (somewhat prematurely, in my mind) based on the assumption that the GPU will fail, hoping that they can get some cash, while letting someone else deal with a potential problem.
Well, that is why we have "caveat emptor", I guess. The OP is still well within his one year of included AppleCare and if they bought the three year plan, well that's even better for the eventual buyer if the unit does, indeed, suffer a GPU failure - which is statistically very unlikely.
And the those who are trying to "offload" their systems are taking a financial hit themselves - especially if they only recently bought the system. So their fear has a direct cost to themselves that is likely higher then the buyer, since the buyer will still be covered under warranty.
