Since I am a cynical old woman, I will tell you that there will be no problem with your selling limits, because your $1000 item will sell to the only bidder at $1.00 because most sensible buyers would suspect the auction is "too good to be true" and will avoid it, while the guy who wins, having actually bid $23.94 because why not, will then claim that the item is Not As Described and demand a partial refund of 99c.
Don't, just don't.
Start your auction at very close to the price you want to get.
Ship with both tracking and Signature Confirmation, and mention in the Description that you will be doing this "for the buyer's protection". (It's really your protection, but it makes an honest buyer feel the warm pink fuzzies, and the scammers move on to a more naive sucker.)
Read the Feedback Left for Others by your bidders, and don't be afraid to cancel the bids of sketchey types or even Block them.
Don't list anything you would be devastated to lose until you have at least 10 DSRs, know what DSRs are, and understand their utter unimportance.
