Thanks for the info everyone. I too thought SE would be rubbish, but although 125 horses per side, because its turbo charged it should be able to maintain these horses to some altitude??? I see it has a 20,000' ME ceiling, but SE performance will be one of my deciding factors.
Yea I have heard of Pureflight, and intend to steer clear of them. The group is a small private group intending to purchase the A/C outright. The TS looks attractive becasue of its low running costs. I'll drop them an email.
Cheers
