A couple weeks ago i checked recent sales on ebay, and there was quite a range of sold prices. The best deals were as low as $300. You'd have to be patient and diligent to pick one up for under $350. I got one for $250 on craigslist, its got a minor display issue and its rough, dinged and paint loss.
