I'm an advocate of the ownership option, if you can go down that route. It means it's your helicopter, available whenever or wherever you want it. You will acquire a close personal affinity and feel for it, with the reassurance that everything is as you want it, to your standards.
Of course there are added costs, commitments and responsibilities, but these are viable if you are doing c.100hr + p.a.
If you can source a 300'C' it is worth the extra, even though it might be an earlier model than the CBi. The extra performance makes a big difference in terms of handling and safety. However, good ones are sought after. Another option might be an Enstrom 280fx.
US$/UK£ exchange rates still make it viable to import from the States, etc. and if you are really quick you may be able to save the vat by going through Denmark.
Alternatively, there may be some bargains and less hassle buying direct in the uk (assuming that's where you are based).
