That lens rattles, all by itself. The front barrel seems loose in its guide rails...cheap canon product aimed at consumers...but, at least the lens works OK.

Tommy Haupfear, I think you'll be a lot happier.
That 10D is a nice tight rig with a pro feel. I'm using it with a 420EX flash (although I wish i had spent the extra $150-200 on the 550EX) and shoot with it almost every day now. I just found out I gotta shoot almost 30 product packs--that's gonna be a good 60 hours of Photoshop time!! (and they want this for the holidays!)
