OK guys (and Annaiso!),
Based on all of the incredible hype about the 28mm f/2, I went and bought a new one from B&H. I had never had a 28mm prime until I bought the 28mm f/2.8 on ebay in early December. I have taken a few rolls of film with the 2.8 and was REALLY impressed with how much better it performed than my old zooms did.
As impressed as I was, people on this and other forums continually trash the 2.8 as a good value for the money but a very average performer. Photodo said better, but hey, all the people on these forums can't be wrong, can they?
I broke down and paid $269 for a new 2.0. I sure hope everyone's advice turns out to be correct. We will see in a few days.
