hi krs...
Choosing the right flight school is really a personal decision and while it is great to get input from fellow pilots and aviation enthusiasts, you'll have to visit the schools and find the one that feels right for you. Also, consider reputation and quality of training programs, cost, location, opportunities for employment at the school (CFI, etc.). While many schools may also advertise affiliations with various regional airlines, I don't think that it is realistic to expect to get into the regionals with only a few hundred hours at this time. You should probably plan on getting instructor ratings or some other time-building experience.
From personal experience, FlightSafety Academy was a great school. I liked the structured 141 training and high quality of instruction, facilities, aircraft, and maintenance. The only thing I didn't like was the high cost. The program there is definitely not for everyone...i knew plenty of people who didn't like FSI.
There are tons of schools all over the US so just figure out what your needs are...perhaps going to your local FBO is more your style than going to a large flight school. There's lots of stuff to consider and many people will tell you good and bad things about every school you consider, but it will ultimately be up to you to decide what works best for you.
best wishes,
