Its the Cheapest way to get a Helicopter rating, by far. It will get you the ticket. But you wont be marketable for some time. Anyway if your a F/W driver you dont need the cut in pay.
Call one of the flight schools or surf places like
www.heli.com . They do the work and can give you the straight scoop. Just remember they make less money off of an add-on, so watch out for any of these schools that give you the "Package Deals".
Good Luck
