Indeed FD, the Diamond DA-40 TDi Star with glass cockpit comes to mind!
Buying a TB9 is ridiculous with the newer options around. Factor in expensive parts (Inconel exhausts anyone?), a crappy old Lycoming (which could be improved with a set of GAMIs and an EGT/CHT monitor), and you're well on your way to parting with £150,000 for god knows what.
Options?
It depends really, what do you want to do with the aircraft? Short hops? Europe-wide stuff? Speed? Amount of pax? Fuel budget? Maintenance budget? Looks?
Nowadays nearly every aircraft will survive outside (TBs have corrosion problems - at least some of them do).
