While i haven't used it much lately, I do love my 70-200 F4L.
It's sharp through out its range and it's fun walking around with a huge lens attached to a small camera. :P
Hi there: just in case you couldn't find the ef-s on fredmiranda. I would give local craigslist a try. I just got mine recently for a good price and the seller let me test the lens first.
you will be surprised that so many people are selling this lens because they got it as part of their T1i / XSi kit.
I am really happy with mine. Good image quality and ultra light weight.
Save for the 70-200/4 IS. In the meantime, the 55-250 IS will do. IMHO a slow tele without IS has a very limited use.
BTW, I had all 70-200 variations and the 70-300 IS. I currently have 135/2 and 300/4 IS (as well as the two lenses you have) and consider adding the 55-250 IS.
