Drakkar,

In the same time, I need a plane
suitable for business trips.


You may know this already, but the kind of business trips you have in
mind will be severely impacted by weather in central Europe (I fly out
of Hamburg, Germany). You will often not be able to do these flights
VFR. However, you may often be able to do them IFR - but you need to
gain experience VFR first, to get your IFR rating.

There are different schools of thinking in this. One is that it might
make sense to do your training from the start in an advanced aircraft
like the Cirrus or the Columbia, and if you proceed to use these
aircraft in accordance with your (growing) abilities and fly with an
instructor often, even after getting the license, you might be flying
safely. The other way of thinking says that it is an unacceptable risk
to start in an aircraft as advanced as that. It all depends on a lot of
factors, like the amount of time and "mental dedication" you can make
available for your flight training. E.g. Lufthansa's basic flight
training is in Beechcraft Bonanzas - a plane comparable in complexity
to the ones you mention. But these students do nothing but learning to
fly, all day long. The average student learns in simpler aircraft.

Have you looked at the Diamond DA-40 TDI? That might be a good
compromise between simplicity and the other factors you mention.
