JH7, you are paying way too much, even for New England standards. I live in Boston, and fly out of KBED which is 15M NW of the city. So probably a 1 hour drive for you.
I pay $124 for the Cessna 172S - brand new equipment, and $45 for my instructor. Instructor rates are the same upto and including the Commercial License. The refurbished 172s are $103, and the 152 is $87.
The 2006 Seminole is $270 an hour including instructor..... just a little more than what you are paying for single engine instruction.
I cannot fault my school, they are highly efficient, exceedingly professional and my instructor, who is just 22, is in my opinion an excellent pilot and teacher.
I highly recommend you schooling at KBED. It's a tower controlled, reasonably busy airport with Pan Am (Clipper Connection) scheduled flights as well as corporate aircraft, and every so often an F-14 taking off since the airbase is there too
PM me if you want to chat a little more, I'd be happy to meet up with you at the school and introduce you to my instructor...or pass along the details and you can contact them directly.
You shouldn't continue to pay the rates you are, especially since your instructor only sees $15 an hour or so.
