HAHA I WISH... I'm in the market for a 580ex flash as well... goodluck because only people letting them go are those getting out of photography as I heard they are the shit!!!

I actually have the 50mm though it feels cheap and is slow to focus the shots are quite sharp. for the price it's a no brainer...

To help you on your quest i know some site that sell those parts used such as adorama (they sell the flashes used)... and I believe cameta camera is have a sale on lenses that you should check out... both are legit sites so no worries...
