Hi,
me too I had these type of question.
If you want FIKI you have just an answer: Mooney. Which one is your choice. But you have to remember that above 180 you need masks and they are oxygen hungry.
If FIKI is not important than cirrus and the cessna 350/400 are quite interesting.
Here too, you have to choose between turbo or not.
I have choosen the 400, but nevertheless I didn't spent so much above 180.
Good thing of the cirrus is that you have a big oxygen bottle (77 cu.ft), bad is the garmin 430,have you even tried to insert a a flight plan in it??
Good of the cessna is the garmin 1000 with the ready pad. Bad the 42 cu.ft. oxygen, this means that you need some kind of oxygen saving device.
last but not least handling. The cessna is utility certfied. Both have the side stick, but cessna behave more straight forward.
