If you are looking at the TBM700 in the future also look at the Eclipse! After its chequered start up history and problems it is turning into a good machine which will get you over the weather and will equal the TBM on running costs with two engined safety.
Under Sikorski 3 to 5 years down the line second hand it should be a strong competitor to the TBM.
