I have used this place to buy several much cheaper monitor cables, Dell toner and iPhone accessories.

Well just recently I got a mini-HDMI to Std HDMI for connecting my 7D to my Phillips 1080P LCD.

These are $20-30 at a store but Monoprice was just $4 and $5 for a 3 ft and 6 ft version.

Enjoy and Merry Christmas
