I'm separating in June of 2015. Right now, I have ~1350 hours. I flew 500 hours last year, so I'm hoping that over the next 16 months I can make it to 2000 hours. All of my time is single engine (T-34C, T-45C, AV-8B, T-6B).

The ExpressJet recruiter said that they could hire me with 25 hours of multi engine time and give me the ATP as part of the training, so I'm going to need to buy at least 25 hours of multi time. Is it worth it for me to buy the remaining 25 hours of multi time in order to get the ATP, or with my total time, am I going to have to go to a regional first anyway, so I might as well save the money and get the multi time and ATP as part of their training?
