Ok, so I looked through some different publications, and conclude the following:

1- All these following aircraft either meet or exceed my range requirements, along with my price range.
2- With all of these because of the price, depending on which one I choose, price wise, I could still keep my Cherokee.
3- These planes, although I guess, some maybe single engine, it still meets my requirements, but I would prefer a twin.

These are the aircraft:

Beech 50 Twin Bonanza
Beech 60 Duke
Cessna 335/340
Cessna 206T
Piper Navajo
Piper Cherokee Six

So, which one would you chose, and why?
