I have recently been accepted to www.launchacademy.co, which is a full stack/Rails developer "bootcamp" in Boston, and I am also interested in this data. Entry level Rails devs get paid differently, regionally. That being said, I know 30 of us have put our life on hold to do this school. I am sure you made the right decision.

EDIT: Quora has a lot of data about this. I am told that junior Rails developers in Boston can expect to make between 70-90k salary starting out. SF and NYC is higher.
