I haven't looked at prices much since about 3 years ago when we bought our
Cherokee, but I would imagine a minimally equipped mid-high time PA28-140 could be had
for $25k

The Cherokee has an extremely benign stall. I almost hesistate to say that it
*does* stall... you have to really provoke it with a aft loading to even get it to
break. It usually just shudders a bit, drops the nose, and auto-recovers while
sinking. The wing is a very stubby airfoil and is fairly symmetrical. Piper designed
the plane to be easy to fly (which it is). The glide ratio by the book is allegedly
the same as 172, (8:1 or so IIRC), but in reality it is not. It glides like a
polished brick. In practice, it's mostly a matter of calibrating your internal
"power-off glide distance" to a Cherokee, though. Not bad once you get dialed in.
Adding wingtips and AMR&D vortex generators help the sink rate a fair bit. Making it
that benign to stall had the tradeoff of bad sink a little more draggy airfoil.

I can't speak for kit planes, except that probably without exception they will

That seems a bit low, even for C150s. I would think mid-high teens for a
comparably ragged-out C150. Remember that a C150 is not the same as a C152. 100 hp
vs. 110, less fuel range, etc. The C150 does fly happily on mogas with nothing more
than a sticker, though.

Most $25k Cherokees won't have fairings. Ours doesn't and I routinely fly
into and out of grass strips. I had a few gravel strips on our trip to Alaska. I
certainly wouldn't call it a "bushplane," but grass strips of 2000' are doable if
you're careful. Of course ours is 180hp, so that helps get rid of some "pucker
factor."

Can't help you there.
