Have you considered getting a desk mount for your monitor. It works pretty well and uses up a lot less space so you can fit in a larger sized monitor. It sucks if your first monitor is 24'' and you have to go to a 19'' for everything to fit.
*edit* nm apparently you want it for cheap and desk mounts are $$$$$ even when they are on sale. Check out craigslist or Kijiji if you want to save some money or fatwallet.com to see if they have any sales.
