I would stay away from Jet U. It is a a big scam. You dount need the jet transition program or whatever they call it.
I went to PEA myself and enjoyed it there. This was 4 years ago, so the prices has skyrocketed since then. I still have a lot of friends instructing there.
I would to ATP. They are quick, pretty good instruction, and lots of multi. I think they have agreements with a few regionals as well...
Hope that helps.
