Like many, I'm sure, I'm still weighing the decision to cast off my 70-200 2.8 IS for the mark II version. About a $900 net cost difference is pretty hard to swallow against a lens that already performs so beautifully.
So a question for those who were mark I owners and upgraded to II; is everyone glad you did it or do some of you feel like you definitely got a better lens but still wonder if it was worth the $'s?
