I agree with Bladecrack & Helinut.
Just to give you an idea Bond charge £1250/hr all in on the 135 & £600/hr on the 135 sim plus VAT of course. With the sim they do say it takes you a minimum of 2hrs to get used to it because it does behave a tad different to the real thing.
I don't know what a 355 costs to rent, but I would say the money is better spent with the 135. IMHO and no I do not work for Bond.
