Man monoprice.com is an amazing site. Got their six foot cables for iPods. Works well and are just $5 vs $20 from apple. Also have a combo cable that has a audio out and power too so I can eliminate out cable.
They have two foot hdmi cables for $6 vs. $20 at places like best buy and they even have a sleeve like the mophie for a battery pack for $17 vs. $60.
And their minidisplay port adapters are $8-9 vs apple at $30.
