Looks like a good listing. I agree with the others who say list a fixed shipping price or use a flat rate box. It takes out the guesswork and makes for a happy customer. We usually set a flat rate price that's the cheapest possible price, maybe even a little lower. The $1 or 2 I may lose on shipping is usually made back in increased bids and happier feedback.
Also consider international shipping. Not sure if there are any int'l buyers for escrap but the additional attention helps.
If you're happy with buy-it-now listings, more power to ya, but for anything that might have more than one interested buyer, a starting bid of 34.99 and 7 day listing wouldn't hurt. Maximizes your chances of a last minute bidder paying a few extra $.
