You can find the spreadsheet on Google Docs by clicking here.
Also, if you click the tab at the bottom of the sheet labeled "Price List," you'll find a complete list of the players and their price movement since early last week. The players are sorted by position and then ranked biggest price drop first (since we're all looking for bargains). Note that the Week 21 prices are a snapshot from the day I assembled the last spreadsheet, and don't account for midweek fluctuations. Still, I think the numbers are pretty accurate, and much more useful than YFF's top three up and down movers.
If you find any errors in the figures please let me know. Enjoy!
