Minimum $20,000 for PPC Campaign

I came across an interesting quote from a BusinessWeek article about the expected monthly costs of a basic paid search campaign:

"Even a search-engine marketing campaign–the most basic means of getting attention–is becoming prohibitive. Ellen Siminoff, CEO of marketing firm Efficient Frontier Inc., estimates that it would cost a startup $20,000 a month now to run a worthwhile campaign, up from $5,000 two years ago. As vets of the dot-com bust might say, welcome to the real world."
