hey there i was in the same position. I recently (2 weeks ago ) got the goljan step 2 audio internel medicine/step 2 review audio on mp3 from ebay. It has 20-1 hour lectures on all the internal medicine topics in context of step 2. a lot of poeple said they are poor quality but they arent bad at all. There are a few lectures that are cut short and the organization is not perfect but in the end you get 1 hour of lecture each lecture on a ton of step 2 material. I find them great.
Also goljan audio for step 1-the pathology series is like 40 1 hour lectures of path stuff but it is all clinical-basically is the same as step 2 stuff. Has like cardiology, GI, etc etc. I got that as well in mp 3 on ebay to listen to and the lectures are the same content as step 2-all clnicial so i would get goljan audio step 1 and step 2.
