Where to begin with Marcion?

If I wanted to learn more about Marcion, especially his version of the Gospel of Luke, where should I begin? I grabbed Jason D. BeDuhn's The First Testament: Marcion's Scriptural Canon (Salem: Polebridge, 2013) from a nearby library. Who else is making waves in this subfield? 

[I'm going to Israel this summer. Are you interested in sponsoring me?]

[Interested in learning more about John the Baptist? Here are some events to attend.]
