Third Party Mini Display Port to VGA or DVI Cables
The cables from Monoprice.com have recently changed so they're not shaped as nicely as before, but the quality is still excellent for the price. 6ft cable for $10 shipped.

The picture isn't faithful to what you'll receive as the Mini Display Port male plug is now a bit bulkier. Still works flawlessly though.
