I have to strenuously disagree with the advice to go in with a range. You are always setting yourself up for the low end. The best approach is to give them a number that is reasonable, but, as BB noted, a little higher than your reservation price, and let them know that you will negotiate if they don't think this is fair. Otherwise, you are negotiating against yourself, which is the cardinal sin of negotiating.
