and looking for a 150/150.
If that's the direction you're taking (and I recommend you do), a 150/150 with long range tanks is a rather large plus.
Long range tanks will eliminate the frustration of having to land for fuel more often than you really want to.
As good as the 150's and 152's are, a 150/150 is a stand alone breed, in and of itself, as this conversion changes the character of the plane.
You find a good one and a love affair will blossom.
