Thanks for the reply, still deciding. That's exactly what I've been thinking, E175 and IAH base sounds good, PHX-IAH hows that commute? But on the CRJ at least there is a chance at some point to get to PHX.

Dallas also has love field with 3-4 flights to PHX on Southwest. And Dulles has a other airports within an hour Reagan and Baltimore with a few flights to PHX.
