Whirlygig is giving some good advices here and I think you will be better of doing training in an piston machine then a turbine. Power management is something I think you will learn better in a piston machine.
I have been reading this thread with interest since I am writing a article for an magazine which is the best training helicopter so keep it coming. :-)
By the way, I have done training in R22, R44, 300CB and C and flown Hiller12C, 206 and MD500.
