Depends what you're doing, but the #1 cost in some startups is the paychecks (check this for example : http://dl.dropbox.com/u/345057/DIASPORA%207312011%20Profit%2...) . If you find a way to survive while coding, you don't need to raise much money (that's what me and my roomate have been doing for 1 year+)

God only knows what we would have done with 200000$ extra :)
