Delta Ng, if i may politely inquire as to why you are so interested in just one manufacturer filling the need? for the money that you would spend on a 900/902, i would imagine that you could pick up a 407 or a b3. these would certainly be cheaper to operate and i'd expect that they would lift more.
i could be wrong about the weight thing but here in canada VIH had/has an EC135 which will lift about the same as a 350BA. it would be hard to get a client to pony up the $4000+ per hour for a machine that can only do so much. i believe the 135 is for sale.
Hughes500/Delta Ng, if you like that way the 500 flies then a 407 might be more up your alley.
just curious (and glad this thread has returned to normal!),
