I know most of you guys know this method, and its the oldest trick in the book. But just want to provide to new people who dont know. First, have $1 deposit in your account, then you start typing in "search: .99" or even better .01 items. Start purchasing these items, and give a feedback for better response time. You can pretty much do this for however much you want to do, just remember to not buy from the same person. It does take some time, but its worth it. As for being a powerseller, do the opposite, and sell paper clips. Rinse & repeat. Hope this helps!
