EDIT: Before you read the first post and blast me for it, I posted this back in 2007, and I currently own this lens and like it, a lot. I am totally over my affliction with plastic lenses!! 
So I just got my 70-200 f/4 IS from B&H, open it up, and I was a little surprised how cheap the lens body feels. I've had 2 of the f/4 non-IS versions and the f/2.8 non-IS and I'm pretty sure that the lens barrels were made out of metal on those, but this lens is obviously made of plastic. Has anyone else noticed this?
I haven't taken any pictures with it yet, so maybe I will change my mind once I do, but I am sort of feeling some buyers remorse here. I mean, this thing is twice the price of the non-IS version, but its built to a cheaper standard? I'm kind of feeling like for this much money I should just take the jump to the f/2.8 IS model and call it a day. 
Am I crazy here?
