I guess it depends where you want to go with your career once you have your inital training out of the way. I know instructors at all of the organisations that have been mentioned here so far, each place has its pros and cons. One thing that you need to think about is the type of equipment that you are trained on. If you want to get into multi engined flying before going into the regionals or other outfits chances are that you will be xposed to conventional twins with steam powered gauges. If you have done all of your training on G1000s and twins missing enough levers
,you may find it difficult to find an operator to take you on. PM me if you want a bit more clarification
