Mark Suster says to raise $100-250k in that case, http://www.bothsidesofthetable.com/2009/08/14/angel-funding-...
And Joshua Schachter (joshu on here) said that companies raising less than 500k are making a huge mistake (http://news.ycombinator.com/item?id=1356345)
Wonder what people on HN who have raised an angel round recently think?
