Sami,

I got into this hunt late, but I read a lot of the posts, and our resident
Mu 2 jockey is spot on.Especially with the suggestion to go for more weather
gear and altitude and less speed. I see you are ready to drop
pressurization, and thats good for several reasons.

If you like everything about the Arrow except speed, you might look into a
Mooney Bravo with TKS. It gets higher, goes faster, and you know how to use
the turbo already, so it will be a natural step up. Not 250, but I believe
220 plus is in the cards.

The Lancair 400 is also a sweet ride. Haven't flown one, but people I trust
are raving about it. Only problem, you cannot get one at any price, gotta
wait.

Any turbo powered Beech might be a good idea.

Lastly, if you really feel the need for speed, the modded planes like the
Rileys could work out, but I am not that familiar with how well they
dispatch. I would try to stick with more conventional power plants if its
for business.

If you could spend more and wait, the D-Jet comes the closest to meeting
your wants. Unfortunately, they haven't even flown a prototype yet. This
plane and its competitors are throwing a lot of FUD into the old turbo prop
market, so waiting to step into that morass would likely be a wise idea.
