When placing a BIN, first go to "What's worth?" in the "Start Selling" page. Take what you think is a fair amount, a bit lower then the lowest sold and use that as your BIN. This would generate interest and a quick sale! Using a reserve is expensive, usually one to five percent of the reserve price, gravy for Ebay. I agree with BG, start the price at what you would want as a minimum, that way it eliminates non serious bidders and gets to the real buyer. For large ticket items, purchase insurance on the part, it's may seem a wast of money, but then why gamble, that's what I usually do.
