Bad timing, my fellow Mac friend. The new MBP is out. People can now pick up a refurb MBP with 2.4GHz, 256MB 8600M, 200GB hard drive for $1349 from Apple.com.
You probably could get a better price on eBay. I sold my old MBP, which had the exact same specs as yours, for $1550 back in June. eBayers aren't as tech savvy as those here on [H].
