You should change your ebay listing to auction style with a reserve price, that way you will get some bids and if it does not sell you can re-list it for free. I don't think you have to end the listing to change it, that way you won't lose those 3 people watching. If you don't get any takers you could always ship it to ebay and let them sell it for you, they take a cut depending on the final selling price. From the eBay Valet page:
"
Fees are deducted from the sale price of your items.
Sale price You earn
Less than $50 60%
$50 to $200 70%
More than $200 80%"
So if they sell it for you for 800, you get to keep $640. If they sell it for you for $1000, you keep $800
