My 2 cents Jason Kolbert (Susquehanna) does a pretty good job from the Conference Calls I've heard him on and especially in the Q&A when Susquehanna had their Conference earlier this year and he hosted the HCV portion. I've seen some critics of Ding Ding (Maxim Group) but have also found many of her questions insightful (though she often goes about things in a cryptic and verbose way).
I tend to judge more the analysts then the company they are with.
