All depends on what you want to do. If you think a MSN will get you to your goal faster, that is the route you should take. For me, I want to get out and working sooner so the ABSN was my choice. All private educations are expensive, just how much can you afford? Also note that many ABSN programs allow you to apply to Masters programs before you leave your current program and start a couple of Masters classes while you're in your ABSN (if you're accepted). I know Loyola and I think UIC allows you to do this.
