Environmental Engineering Graduate College Decision - Johns Hopkins, UC Berkeley, or Virginia Tech?

Dear friends, I am trying to decide by Friday which school to get my Master of Science in Environmental Engineering from. I have been accepted into Johns Hopkins University, UC Berkeley, and Virginia Tech. US News Rankings: Johns Hopkins is #3-5, Berkeley is consistently #2. Virginia Tech is # 11-13. I am currently attending VA Tech (since Aug 2006) but spent the past 2 semesters taking 38 credits of background engineering cles (Fluid Mechanics, etc.). Regardless of choice, I should graduate in May 2008. Relative Costs until graduation: Virginia Tech: $8,000. Johns Hopkins: $25,000. Berkeley: $55,000. Virginia Tech is the only ABET accredited Master's degree, which helps me be an engineer because my BS is in Economics from UPenn. I like being surrounded by greatness, which I do not often find at Tech. No school has faculty who 100% align with my research interests. JHU is 1 hour from home vs Tech is 4. I want to be a consultant then CEO of my own company. I want a PhD eventually.
