I hope it goes well. I've had several bad auctions over the years, unfortunately.

I research the current auctions and recent past auctions to get an idea of what people or paying for items like mine. Then I come up with a reasonable amount I'm happy with. I go overboard on the photos, and as a enthusiast photographer I take plenty of professional quality photos and write my own HTML page rather than use eBays default ones. I make my auction page as professional as possible. I'm flabbergasted by most of the auction pages I see where it is difficult to see what they are actually selling. So I make mine great looking, appealing, informative, and honest (point out all deficiencies.) I've discovered over the years that I average a bit more with the Buy Now than I do with bidding auctions. And I usually get the deal done within a few hours after posting the item. I frequently sell my item in hours while others who have the same item and at a lesser amount often have their auction still going after a week or two. I think a lot depends on how well you market the item. A great TV commercial will sell junk really well, but a crappy ad might not be able to move great items. People are funny like that. Make the page look great with very nice photos that make the item look appealing, and people lose control and hit the Buy Now button! A lot of it is the psychology of selling. I think when people see my professional looking pages they think I'm a business selling items and probably feel more comfortable dealing with me than with a guy who took a dark, fuzzy photo with his outdated phone and posted that with a bunch of gibberish.
