I promise I'm not trying to pile on here... but the others are not trying to undercut you.

I would value it around $300ish too... and that only if I was within driving distance. You should probably do better on ebay or craigslist but be warned that if your EBAY customer is not happy you end up eating the shipping cost and possibly getting a broken machine back after the 2-way trip (don't ask me how I know this)

Sorry not to have better news- but if you sell it here on the site you are probably not going to get anywhere near your asking price.
